Understand sampling distributions and the Central Limit Theorem for Proportions Question A small community college has a population of 986 students, 252 of whom them are considered non-traditional students. Find the population proportion, as well as the mean and standard deviation of the sampling distribution for samples of size n 40 Round all answers to 3 decimal places. Provide your answer below: No Provieus ) 10 e hp

Please a, b and c

Find the margin of error for the given values of​ c, s, and n.   cequals=0.99 sequals=3.9 nequals=15   view the​ t-distribution table. The margin of error is​(Round to one decimal place as​ needed.)

Assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1. Draw a graph and find the probability of a bone density test score greater than - 1.89. Sketch the region. Choose the correct graph below. O A. OB. C. O D. 1,89 -1.89 -1.89 -1.89 1,89 The probability is (Round to four decimal places as needed.)

Assume that a sample is used to estimate a population proportion p. Find the margin of error E that corresponds to the given statistics and confidence level. Round the margin of error to four decimal places.95% confidence; n = 380, x = 50 Group of answer choices 0.0408 0.0306 0.0340 0.0357
