Question

1. Table #7.3.7contains pulse rates after running for 1 minute, collected from females who drink alcohol ("Pulse rates before," 2013). The mean pulse rate after running for 1 minute of females who do not drinkis 97 beats per minute. Do the data show that the mean pulse rate of females who do drink alcohol is higher than the mean pulse rate of females who do not drink? Test at the 5% level.

176	160	120	72	60	74
150	120	120	77	67	68
150	125	68	84	59
115	89	87	92	64
129	132	88	80	88

Answer 1

The hypothesis being tested is:

H0: µ = 97

Ha: µ > 97

97.000	hypothesized value
100.519	mean Data
33.561	std. dev.
6.459	std. error
27	n
26	df
0.545	t
.2953	p-value (one-tailed, upper)

The test statistic is 0.545.

The p-value is 0.2953.

Since the p-value (0.2953) is greater than the significance level (0.05), we fail to reject the null hypothesis.

Therefore, we cannot conclude that the mean pulse rate of females who do drink alcohol is higher than the mean pulse rate of females who do not drink.

Please give me a thumbs-up if this helps you out. Thank you!
