Transcribed Image Text:The accompanying table lists body temperatures (in °F) obtained from randomly selected subjects. Using a 0.05 significance level, test for an interaction between gender and smoking, test for an effect from gender, and test for an effect from
smoking. What do you conclude?
First test for an interaction between the two factors. Determine the null and alternative hypotheses. Choose the correct answer below.
A. Ho: Body temperatures are not affected by gender.
H,: Body temperatures are affected by gender.
B. Họ: Body temperatures are affected by an interaction between gender and smoking.
H, : Body temperatures are not affected by an interaction between gender and smoking.
Body Temperature Data
C. Ho: Body temperatures are not affected by smoking.
H,: Body temperatures are affected by smoking.
Smokes
Does not smoke
O D. Ho: Body temperatures are not affected by an interaction between gender and smoking.
Female
98.7 97.6 98.1 98.5
98.4 97.8 97.9 96.9
H,: Body temperatures are affected by an interaction between gender and smoking.
Male
97.9 98.5 98.3 98.6
97.7 97.9 98.3 99.1
Determine the test statistic.
The test statistic is

Done
(Round to two decimal places as needed.)
Determine the P-value.
The P-value is.
(Round to three decimal places as needed.)
Determine the proper conclusion at the 0.05 significance level. Choose the correct answer below.
O A. Reject Ho. There is sufficient evidence to support the alternative hypothesis. There does not appear to be an interaction between gender and smoking.
B. Fail to reject Ho. There is insufficient evidence to support the alternative hypothesis. There appears to be an interaction between gender and smoking.
C. Fail to reject Ho. There is insufficient evidence to support the alternative hypothesis. There does not appear to be an interaction between gender and smoking.
D. Reject Ho. There is sufficient evidence to support the alternative hypothesis. There appears to be an interaction between gender and smoking.
Transcribed Image Text:If appropriate, test for an effect from gender. Choose the correct answer below.
A. Ho: Smokers and non-smokers people have different population mean body temperatures.
H,: Smokers and non-smokers people have the same population mean body temperature.
B. Ho: Men and women have the same population mean body temperature.
: Men and women have different population mean body temperatures.
H1:
O C. Ho: Men and women have different population mean body temperatures.
H,: Men and women have the same population mean body temperature.
O D. Ho: Smokers and non-smokers have the same population mean body temperature.
H,: Smokers and non-smokers people have different population mean body temperatures.
O E. This test is not appropriate due to the results of the test for interaction between the two factors.
If appropriate, determine the test statistic. Select the correct choice below and, if necessary, fill in the answer box within your choice.
A. The test statistic is
(Round to two decimal places as needed.)
