Snow avalanches can be a real problem for travelers in the western United States and Canada. A very common type of avalanche is called the slab avalanche. These have been studied extensively by David McClung, a professor of civil engineering at the University of British Columbia. Suppose slab avalanches studied in a region of Canada had an average thickness of μ = 68 cm. The ski patrol at Vail, Colorado, is studying slab avalanches in its region. A random sample...

Historically, the population of wolves in Canada have been found to have an average adult weight of 38.9 kilograms. The Canadian Wildlife Service believes that due to climate change, this may have increased. A random sample of 12 wolves is captured and weighed and the following results are obtained. Assume that the weights are normally distributed: 44.8, 40.7, 42.6, 46.8, 48.7, 35.4, 38.9, 39.5, 38.3, 48.9, 48.4, 38.4. At a 0.05 significance level, test the hypothesis that the average weight...

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...

Women athletes at the a certain university have a long-term
graduation rate of 67%. Over the past several years, a random
sample of 37 women athletes at the school showed that 23 eventually
graduated. Does this indicate that the population proportion of
women athletes who graduate from the university is now less than
67%? Use a 10% level of significance.
(a) What is the level of significance?
State the null and alternate hypotheses.
