It seems these days that college graduates who are employed full-time work more than 40-hour weeks. Data are available that can help us decide if this is true. A survey was recently sent to a group of adults selected at random. There were 11 respondents who were college graduates employed full-time. The mean number of hours worked per week by these 11 respondents was 42 hours, with a standard deviation of 9 hours. Assume that the population of hours worked per week by college graduates employed full-time is normally distributed with mean we conclude that u is greater than 40 hours? Use the 0.05 level of significance. Can H. Perform a one-tailed test. Then fill in the table below.

4) In 2015, the mean household expenditure for energy was $ 1493 according to data published by the US Energy Information Association. Pratap is an economist and he thinks that this has changed significantly in 2018. In a random sample of 35 households he found that the mean expenditure for energy was $1618 with a standard deviation of $321. At the 5 % level of significance can we agree with Pratap?
It seems these days that college graduates who are employed full-time work more than 40-hour weeks. Data are available that can help us decide if this is true. A survey was recently sent to a group of adults selected at random. There were 13 respondents who were college graduates employed full-time. The mean number of hours worked per week by these 13 respondents was 42 hours, with a standard deviation of 8 hours. Assume that the population of hours worked per week by college graduates employed full-time is normally distributed with mean u. Can we conclude that u is greater than 40 hours?

Americans (on average) individually eat 16 pounds of seafood each year with a standard deviation of 7 pounds. James samples 40 Americans and finds and average of 14 pounds. How likely is it to get an average of 14 pounds if he had a representative sample?
A nutritionist conducted a study on the eating patterns of early adolescent boys and girls. Calorie intake is normally distributed for both boys and girls. The population means are 3300 calories per day for boys and 2900 calories per day for girls. The population standard deviations are 790 for boys and 720 for girls. The nutritionist believes that children may have an eating disorder if they are in the bottom 2% the distribution. Based on this, if a child’s intake is1600 calories per day, should the nutritionist be concerned that this child may have an eating disorder? (Compute for each gender separately). Does it make a difference if this child is a boy or a girl? Explain your answer. What proportion of girls consume between 2000 and 2400 calories per day? Is the proportion of boys who consume between 2000 and 2400 calories per day the same, higher, or lower than the proportion of girls who consume between 2000 and 2400 calories per day? Explain your answer.
It seems these days that college graduates who are employed full-time work more than 40-hour weeks. Data are available that can help us decide if this is true. A survey was recently sent to a group of adults selected at random. There were 10 respondents who were college graduates employed full-time.

A student will spend 15 hours average each week in class. If the standard deviation is 2 hours, what percentage of students spend less than 12 hours in class?
Lucille, Rocio, and Cristina are all taking College Mathematics but from different professors. They all recently took a statistics exam and the exam scores were normally distributed in each of their classes. Lucille's class had an average grade of 85 and the standard deviation was 3. Lucille earned 89.5 on the exam. Rocio's class had an average grade of 83 and the standard deviation was 4. Rocio earned 87.4 on the exam. Cristina's class had an average grade of 76 and the standard deviation was 6. Cristina earned 79.3 on the exam. Since some professors give harder exams than others, these students decided to use statistics to figure out who did the best on their exam.
Suppose that the quarterly sales levels among health care information systems companies are approximately normally distributed with a mean of 10 million dollars and a standard deviation of 1.2 million dollars. One health care information systems company considers a quarter a "failure" if its sales level that quarter is in the bottom 15% of all quarterly sales levels. Determine the sales level (in millions of dollars) that is the cutoff between quarters that are considered "failures" by that company and quarters that are not. Carry your intermediate computations to at least four decimal places. Round your answer to one decimal place. ☐ million dollars X 5
In Australia, young people aged 18 to 29 have an average of 394 Facebook friends. This population distribution takes only integer values, so it is certainly not Normal. It is also highly skewed to the right. Suppose that = 280 and you take an SRS of 70 Facebook users from this population. Findings from "Yellow social media report 2018. Part one: -Consumers, published by Yellow and available at www.yellow.com.au/wp- content/uploads/2018/06/Yellow-Social-Media-Report-2018- Consumer.pdf. Attempt 2 Side-by-Side For your sample, what are the mean and standard deviation of x, the mean number of friends per user? Use decimal notation. Give your answers to two decimal places if necessary.
Suppose that the quarterly sales levels among healthcare information systems companies are approximately normally distributed with a mean of 12 million dollars and a standard deviation of 1.1 million dollars. One health care information systems company considers a quarter a "failure" if its sales level that quarter is in the bottom 15% of all quarterly sales levels. Determine the sales level (in millions of dollars) that is the cutoff between quarters that are considered "failures" by that company and quarters that are not. Carry your intermediate computations to at least four decimal places. Round your answer to one decimal place.
A recent study found that 69% of all adults over 50 wear sunglasses for driving. In a random sample of 20 adults over 50, what is the mean and standard deviation of those that wear sunglasses?

A survey was recently sent to a group of adults selected at random. There were 15 respondents who were college graduates employed full-time. The mean number of hours worked per week by these 15 respondents was 43 hours, with a standard deviation of 8 hours. Assume that the population of hours worked per week by college graduates employed full-time is normally distributed with mean μ. Can we conclude that μ is greater than 40 hours? Use the 0.05 level of significance. State the null hypothesis H0 and the alternative hypothesis H1 Find the t-test df & Solve the t-test value Find the critical value Can we conclude, at the 0.05 level of significance, that the mean number of hours worked per week by college graduates is greater than 40 hours? Yes or No?
