2a. (1 pt). Calculate the standard error for μ=89 and σ=43 if the sample size is 14.

2b. (1pt). Suppose your z statistic is -1.5. What is the p value for a two-tailed test?

2c. (1 pt). If you draw a random sample of size 30 with a mean of 109 from a population that has a mean of 121 and a standard deviation of 9, what is your effect size?

2d. (1 pt). Refer to Question 2c. Calculate a 90% confidence interval for your sample data. Does it include the population mean?

The population has mean μ=29 and standard deviation σ=9. This distribution is shown with the black dotted line. We are asked for the mean and standard deviation of the sampling distribution for a sample of size 34. The Central Limit Theorem states that the sample mean of a sample of size n is normally distributed with mean μx¯=μ and σx¯=σn√. In our case, we have μ=29, σ=9, and n=34. So, μx¯=29 and σx¯=934‾‾‾√=1.5 This distribution is shown with the red...
