Question 4>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?NoYesIf the conditions for normality are met, give the upper and lower bounds for the middle 68 percent of possiblesample proportions ROUNDED TO TWO DECIMAL PLACES. Put the smaller number first, then the largernumber (Use the 68-95-99.7 rule here, not the exact value. If they are not met, enter DNE.)Submit Question

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:

Please state if the statement is correct or wrong and explain why. Statement 1. The sampling distribution of the sample mean with a sample size of 12 has a smaller standard error than that of the sampling distribution of the sample mean with a sample size of 13. Statement 2. Degrees of Freedom is one of the parameters of the normal distribution. Statement 3. A parameter is a function of a sample.

Angela recently discovered that the proportion of cat owners in Scranton, Pennsylvania, is 0.27. Suppose Angela were to select a random sample of n = 200 Scranton residents and determine the proportion within the sample who are cat owners. If this sampling process is repeated many times, we can build a sampling distribution. We know in this case the sampling distribution will be Normal in shape and will have a standard deviation equal to approximately ___________.
