BRED001 Week 6 Problem solving _ sampling distribution of the sample mean
Numerical
Suppose that during any hour in a large department store, the average number of shoppers is 448, with a standard deviation of 21 shoppers. 2. What is the probability that a random sample of 49 different shopping hours will yield a sample mean between 441 and 446 shoppers?

Question at position 18 Imagine that we draw samples from the same population of normally distributed scores with a mean of 100 (μ= 100) and SD of 10 (σ = 10). First, we create a histogram for the distribution of sample means (DOSM) for a sample size of 30 (n=30). Next, we create a second distribution of sample means for a sample size of 300 (n=300). Please check the true statements below (you may check more than one).Both DOSMs will have a relatively normal distribution.The DOSM for a sample size of n=30 will have a higher mean than the DOSM for a sample size of n=300.Neither DOSMs will have a normal distribution.The DOSM for a sample size of n=30 will have a larger standard error than the DOSM for a sample size of n=300.Both DOSMs will have a standard error of 10.Both DOSMs will have a mean of 100.
