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	76	56	72	64	68	68	88	76	72
Female	68	104	104	96	72	60	60	96	84	124

Construct a 95​% confidence interval estimate of the mean pulse rate for males.

< μ <

Answer 1

	Males ( X )
	96	501.76
	76	5.76
	56	309.76
	72	2.56
	64	92.16
	68	31.36
	68	31.36
	88	207.36
	76	5.76
	72	2.56
Total	736	1190.4

Confidence Interval



Lower Limit =
Lower Limit = 65.3729
Upper Limit =
Upper Limit = 81.8271
95% Confidence interval is ( 65.3729 , 81.8271 )

65.3729 <   <  81.8271 .
