opose are running a study/poll about the probability of a true negative on a test for a certain cancer. You ndomly sample 109 people and find that 71 of them match the condition you are testing. opose you have the following null and alternative hypotheses for a test you are running: p:p= 0.6 a:p+ 0.6 lculate the test statistic, rounded to 3 decimal places 1.09 x o

I need help asap. This is the question.  A recent study at a local college claimed that the porportion, p, of students  who commute more than 15 miles to school  is no more than 15% . If a random  sample of 175 students  at this college  is selected,  and it is found that 86 commute more than 15 miles to school, can we reject the college's claim at the 0.05 level of significance.  Perform 1 failed test then fill in the table below

Alex wonders if the same proportion of people are left-handed in the United States and Canada. He wants to obtain a random sample of people from each country to test if there is a significant difference between the proportion of left-handed people in each country. Which of the following is an appropriate set of hypotheses for Alex's significance test? Ho: pU.S. - pC = 0 Ha pU.S.-pC 0

Let's say you survey a random sample of people. You find that 53% prefer apples over oranges. You make a 90% confidence interval for the proportion of people who prefer apples. The resulting confidence interval is: 0.448 to 0.612 Based on this interval, assess the following statement: There is a 90% probability that the proportion of people who prefer apples over oranges is between 0.448 and 0.612. is it true or false

According to the Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in 2007 were for identity theft. This year, a certain state kept track of the number of its 1325 complaints were for identity theft. They want to know if the data provide enough evidence to show that this state had a different proportion of identity theft than 23%? State the random variable, population parameter, and hypotheses. The symbol for the random variable involved in this problem is            The wording for the random variable in context is as follows:           The symbol for the parameter involved in this problem is            The wording for the parameter in context is as follows:

A news article that you read stated that 54% of voters prefer the Democratic candidate. You think that the actual percent is smaller. 102 of the 221 voters that you surveyed said that they prefer the Democratic candidate. What can be concluded at the 0.10 level of significance?For this study, we should use The null and alternative hypotheses would be: Ho: (please enter a decimal) H1: (Please enter a decimal)The test statistic = (please show your answer to 3 decimal places.)The p-value = (Please show your answer to 4 decimal places.)The p-value is ααBased on this, we should the null hypothesis.Thus, the final conclusion is that ... The data suggest the population proportion is not significantly smaller 54% at αα= 0.10, so there is not sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is smaller 54%.The data suggest the populaton proportion is significantly smaller 54% at αα= 0.10, so there is sufficient evidence to conclude that the…

An ANOVA test is conducted of the grades earned by students from a math professor, who taught 3 sections of the same class: morning, afternoon and evening. The decision was to Reject the null hypothesis. Does the test tell which mean is significantly different? yes O no
