Question

A physician wants to develop criteria for determining whether a patient's pulse rate is atypical, and she wants to determine whether there are significant differences between males and females. Use the sample pulse rates below. Male 96 60 64 72 76 84 68 88 76 88 Female 84 88 104 88 60 84 60 104 96 124 Click here to view a t distribution table. LOADING...

Construct a 95% confidence interval estimate of the mean pulse rate for males. 68.9less thanmuless than 85.5 (Round to one decimal place as needed.) b. Construct a 95% confidence interval estimate of the mean pulse rate for females. nothingless thanmuless than nothing

Explanation / Answer

(1-alpha)*100% confidence interval for population mean=sample mean±t(alpha/2,n-1)*sd/sqrt(n)

95% confidence interval for population mean=mean±t(0.05/2, n-1)*sd/sqrt(n)

for male

for female

95% confidence interval estimate of the mean pulse rate for females 75.2<mu<103.2

male female 96 84 60 88 64 104 72 88 76 60 84 84 68 60 88 104 76 96 88 124 n 10 10 mean 77.2 89.2 sd 11.63 19.60
