After deducting grants based on need, the average cost to attend the University of Southern California (USC) is $29,925. Assume the population standarddeviation is $6,500. Suppose that a random sample of 50 USC students will be taken from this population. Use z-table.a. What is the value of the standard error of the mean?(to nearest whole number)b. What is the probability that the sample mean will be more than $29,925?(to 2 decimals)c. What is the probability that the sample mean will be within $1,500 of the population mean?(to 4 decimals)d. How would the probability in part (c) change if the sample size were increased to 160?(to 4 decimals)

As per our guidelines we are supposed to answer only first 3 sub-parts. Please upload 4 th part (d)…

An Excel assignment counts for 0-10 points. The scores in a class of 12 students are recorded as follows:1 5 5 6 7 7 8 8 8 9 10 10 What is the deviation of the score 10 from the mean in 13a (recall that this involves a subtraction of the mean from the particular score)? I think I got answer but want to check.
7.2.29-T Question Help An IQ test is designed so that the mean is 100 and the standard deviation is 19 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 99% confidence that the sample mean is within 6 IQ points of the true mean. Assume that o = 19 and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation. The required sample size is.

X 6.3.10 Question Help Three randomly selected households are surveyed. The numbers of people in the households are 2, 4, and 9. Assume that samples of size n = 2 are randomly selected with replacement from the population of 2, 4, and 9. Construct a probability distribution table that describes the sampling distribution of the proportion of odd numbers when samples of sizes n= 2 are randomly selected. Does the mean of the sample proportions equal the proportion of odd numbers in the population? Do the sample proportions target the value of the population proportion? Does the sample proportion make a good estimator of the population proportion? Listed below are the nine possible samples. 2,2 2,4 2,9 4,2 4,4 4,9 9,2 9,4 9,9 Construct the probability distribution table. Sample Proportion Probability (Type an integer or fraction.)
