Q1- When using a Bonferroni correction to get an overall Type I error rate of = 0.05, the significance level is divided by:

Group of answer choices

1-the number of pairs of groups that are being compared.

2-the number of groups in the study.

3-the number of observations in the study.

Q2 A study was carried out to investigate physiological responses to psychological challenges when surrounded with social support. Forty-five women were randomly assigned to one of three groups: support from their pet dog, support from a human friend, or no support from their pet dog or human friend (control). One of the physiological responses monitored was heart rate (beats per minute) while participants were exposed to a psychological stressor (mental arithmetic). The results are presented in the table below.

	Pet Group (n = 15)	Friend Group (n = 15)	Control Group (n = 15)	Test statistic	p-value
Heart rate (bpm), mean (SD)	73.48 (9.97)	91.33 (8.34)	82.53 (9.24)	F2, 42 = 14.08	< 0.001

The appropriate null hypothesis for this situation is all social support groups have the same average heart rate when exposed to a psychological stressor.
