Overall, the proportion of the student body at a college supporting more funding for student clubs is 0.35. Suppose that we take samples of 45 students. What is the mean of the sampling distribution for this sample proportion? What is the standard deviation of the sampling distribution? Round the answer to three decimal places. Does this sample size and proportion meet the conditions for normality the sampling distribution? O No Yes If the conditions for normality are met, give the upper and lower bounds for the middle 68 percent of possible sample proportions ROUNDED TO TWO DECIMAL PLACES. Put the smaller number first, then the larger number (Use the 68-95-99.7 rule here, not the exact value. If they are not met, enter DNE.)

Calories consumed by members of a track team the day before a race are normally distributed, with a mean of 1,800 calories and a standard deviation of 100 calories. If a normal curve is sketched using these data, what is the range for 3 standard deviations to the right and to the left of the mean? Group of answer choices 0–3,600 1,700–1,900 1,600–2,000 1,500–2,100

Use the Central Limit Theorem to find the mean and standard error of the mean of the sampling distribution. Then sketch a graph of the sampling distribution.   The mean price of photo printers on a website is ​$227 with a standard deviation of ​$58. Random samples of size 22 are drawn from this population and the mean of each sample is determined.       Question content area bottom Part 1 The mean of the distribution of sample means is enter your response here   . Part 2 The standard deviation of the distribution of sample means is enter your response here   . ​(Type an integer or decimal rounded to three decimal places as​ needed.)

An insurance company is looking over accident statistics. They want to model the population of all drivers for the population parameter of the standard deviation and variance of the age of the driver involved in an automobile accident. They have a sample of 100 accidents from around the country. The age of the driver in each of these accidents is provided below. Use Excel to calculate the sample standard deviation and the sample variance. Round your answers to one decimal place. Do not round until you've calculated your final answer "Age of people in accident"48643346436728189044472440202747683248472248217347302918487364454920205066654187873417203176493089672222455023481746382942254720463119214227226621236675744621461969202048238851284918204522313823284939   Standard deviation:  Variance:
