Angela recently discovered that the proportion of cat owners in Scranton, Pennsylvania, is 0.29. Suppose Angela were to select a random sample of \( n = 125 \) 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 that sampling distribution will be Normal, with a mean of 0.29 and a standard deviation of ________.Options:A. 0.0894B. 0.0023C. 0.2059D. 0.0016E. 0.0406

Suppose that a study of elementary school students reports that the main age at which children begin reading is 5.9 years with the standard deviation of 0.8 years. If a sampling distribution is created using samples of the ages at which 68 children began reading, what would be the mean of the sampling distribution of sample mean? Round to 2 decimal places, if necessary

Joan’s finishing time for the Bolder Boulder 10K race was 1.67 standard deviations faster than the women’s average for her age group. There were 415 women who ran in her age group. Assuming a normal distribution, how many women ran faster than Joan?
Suppose that the lengths of pregnancies are normally distributed with a mean of 270 days and a standard deviation of 14 days. If a child is born in the lower 4.5% of this distribution is considered to be premature, how many days must a pregnancy last for a child to not be considered premature? (Round to the nearest day.)

. Pyramid Lake is on the Paiute Indian Reservation in Nevada. The lake is famous for cutthroat trout. Suppose a friend tells you that the average length of trout caught in Pyramid Lake is ? = 19 inches. However, the Creel Survey reported that of a random sample of 49 fish caught, themean length was ?̅= 18.5 inches, with estimated standard deviation ? = 3.2 inches. Do these data indicate that the average length of a trout caught in Pyramid Lake is less than ? = 19 inches? Use ? = 0.05.a. Do we use a Normal or a Student’s t- distribution? Explain. How many degrees of freedom do we use?b. What are the hypotheses?

A government sample survey plans to measure the total cholesterol level of an SRS of men aged 20-34.Suppose that, in fact, the total cholesterol level of all men aged 20-34 follows the Normal distribution with mean M = 182milligrams per deciliter (mg/dL.) and standard deviation G = 37 mg/dL.0 Attempt 4(a) Choose an SRS of 100 men from this population. What is the sampling distribution of &? (Use the units of my/dL.)
The first experiment I created 200 samples with 10 students in each and took each sample's mean. The mean of this distribution was about 10.7 miles with a standard deviation of 3.7 miles. (See video) Next I did 200 samples with 20 students each, then I did 200 samples with 50 students each and finally I did 200 samples with 100 students each. Watch the following video and answer the following questions about the sampling distributions being created. 1) For the samples with 100 students each, when the sampling is complete, what will the mean be close to or equal to? 2) For the samples with 100 students each, when the sampling is complete, will the standard deviation be smaller than the standard deviation for the samples with 50 students each? 3) What is the mean of the population of students that I am randomly sampling from? 4) What is the name of the important theorem that I am demonstrating right now.?
