Open the "Lab Dataset" (HSCI390.sav) you have been using for lab assignments in SPSS. Your analysis will focus on the variables "Gender" (Gender) and "Blood Alcohol Content at last drinking episode" (BAC). Researchers are interested in examining if the mean Blood Alcohol Content at last drinking episode differs between men and women. To examine their research question of interest, they will use data from the sample of CSUN students contained in the HSCI390.sav dataset. Using SPSS for the analysis, you will test whether there appears to be a difference in the population mean Blood Alcohol Content at last drinking episode of men compared with population mean of women, using an alpha level (α) of 0.01. You will use the information above for several of the following questions. 

Use the data from above examining whether there appears to be a difference in the population mean Blood Alcohol Content at last drinking episode of men compared with population mean of women. Which of the following represents the appropriate alternative hypothesis (H1), given this research question of interest?

Use the data from above examining whether there appears to be a difference in the population mean Blood Alcohol Content at last drinking episode of men compared with population mean of women. What is the degrees of freedom (df) associated with your test? 

Use the data from above examining whether there appears to be a difference in the population mean Blood Alcohol Content at last drinking episode of men compared with population mean of women. Which of the following represents the appropriate decision rule and critical values, testing at an alpha level (α) of 0.01.

Use the data from above examining whether there appears to be a difference in the population mean Blood Alcohol Content at last drinking episode of men compared with population mean of women. What is the t-statistic associated with your test? (rounded to the nearest thousandth)

Use the data from above examining whether there appears to be a difference in the population mean Blood Alcohol Content at last drinking episode of men compared with population mean of women. What is the p-value associated with your test? (rounded to the nearest thousandth)

Use the data from above examining whether there appears to be a difference in the population mean Blood Alcohol Content at last drinking episode of men compared with population mean of women. Given your test results, what is your decision about the null hypothesis?

Use the data from above examining whether there appears to be a difference in the population mean Blood Alcohol Content at last drinking episode of men compared with population mean of women. Interpret your decision about the null hypothesis from the previous question.
