In a random sample a 36 Bozemanites, the average pounds of beef consumed in 2017 was 98.4 with a standard deviation of 3.4 pounds. Calculate the margin of error for a 95% confidence interval for ? = true average pounds of beef consumed by Bozemanites in 2017. You will need to use R to obtain the appropriate multiplier.

1a. A random sample of 29 BSN nurses at a large Michigan hospital have the average (mean) hourly wage of $37.55 with the standard deviation of $4.66. If we want a 99% confidence interval to have a margin of error of no more than $3, what is the minimum required sample size we should take? (Hint: use t*=2.7633) 1b. A test of the hypotheses H0: mu=17 vs. Ha: mu >17 is conducted. Sample data of n=30 cases provides x-bar=14 with...
