Answer 1

calculate mean and standard deviation of the given data.

Hypothesis testing

a) Null and alternative hypotheses

b) Value of the test statistic

c) p-value is

p(t>2.066) = 0.021-------------@df = n-1=79

d)

Hence,we have sufficient evidence to believe the mean pulse rate is higher than 70.

e)

shape of distribution is Bell Shaped Distribution.
