Question:

In the ambulance response time example (Exercise 8), a $95 \%$ confidence interval was constructed for $N=67$ ambulance runs. Assuming the mean and standard deviation remained the same $(\bar{X}=8.51, s=6.64) \ldots$

a. What is the confidence interval for the mean for $N=125$ ambulance runs rather than 67 ?

b. What is the confidence interval for the mean for $N=33$ ambulance runs rather than 67 ?

c. How do these two confidence intervals compare with the $95 \%$ confidence interval of $(6.89,10.13)$ calculated in Exercise 8 ?
