Expert Solution

Step 1
Given Information:
Number of campers randomly selected, n =33
Avarege numple of peope prefer to camp at beach, Mean = 27
Standard deviation = 7.4
Confidence level = 95%
Step 2
Given the confidence level 95% or 0.95, the level of significance is evaluated as
Next we obtain the critical value of from the t distribution table.
