Question
Decision rule: reject the null hypothesis (H0) if the pvalue is less than or equal to _.
The test statistic is calculated to be _?
The pvalue is then found to be_?
This leads to making the decision to _ the null hypothesis.
In summary using _ level of significance there is _ (enough or insufficient) evidence to conclude that the mean pulse rate among all adults when sitting is lower than the mean pulse rate among all adults when standing.
QUESTION 17 Saved A nursing student took a random sample of adults and recorded their pulse rate while sitting The student then found another random sample of adults and recorded their pulse rates while standing Can the stomenet con lude a s%h lave of signiricance fox this eercis stading.among all dis?

Decision rule: reject the null hypothesis (H0) if the pvalue is less than or equal to level of significance
The test is for independent samples:
The test statistic is t = -1.59
The pvalue is then found to be = 0.0626
This leads to making the decision to Fail to reject H0 the null hypothesis.
In summary using 5% level of significance there is insufficient evidence to conclude that the mean pulse rate among all adults when sitting is lower than the mean pulse rate among all adults when standing.
