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.

选项
A.Both DOSMs will have a relatively normal distribution.
B.The DOSM for a sample size of n=30 will have a higher mean than the DOSM for a sample size of n=300.
C.Neither DOSMs will have a normal distribution.
D.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.
E.Both DOSMs will have a standard error of 10.
F.Both DOSMs will have a mean of 100.

In this scenario, we are examining the sampling distribution of the sample means (DOSM) for two different sample sizes drawn from a normal population with μ = 100 and σ = 10. Option 1: 'Both DOSMs will have a relatively normal distribution.' Since the underlying population is normal, the sampling distribution of the ......Login to view full explanation
