Question

A physician wants to develop criteria for determining whether a patients pulse rate is atypical and she wants to determine whether there are significant differences between males and females use the sample pulse rates below males 96 60 84 84 60 76 76 88 72 88 construct a 95% interval estimate of the mean pulse rate for males

Answer 1

Following table shows the calculations for mean and SD of sample:

	X	(X-mean)^2
	96	309.76
	60	338.56
	84	31.36
	84	31.36
	60	338.56
	76	5.76
	76	5.76
	88	92.16
	72	40.96
	88	92.16
Total	784	1286.4

Sample size: n=10

The sample mean is

The sample standard deviation is
