Suppose we wanted to know if there is a difference in the proportion of citizens from different provinces who would support the idea of federal laws for mask wearing in public. Upon collecting some sample data we find that 34 out of 50 residents of Ontario would support such legislation, while only 28 out of 50 residents of Alberta support the idea of such laws.
a.) Conduct the appropriate test of hypothesis for these data at the .05 level
b.) What is the p-value associated with these data?
c.) Generate a 90% confidence interval for these data
d.) Why is z always the test statistic used with a proportion, rather than t?

We want to know whether or not there is a difference in the
proportion of A’s in math class received by students who
participated in a tutoring program and those who did not
participate. There are 40 kids who did the tutoring program and 14
of them got A’s. There are 52 who did not do the tutoring program
and 12 of them also got A’s. Apply 2-sided test at 4% SL.

A researcher wanted to see whether there was a difference
between NYC citizens and Boston citizens in the amount of time (in
hours) they spent outside during April 2020. He collected two
samples – one of NYC citizens and the other of Boston citizens, and
measured the amount of time each subject spent outside during April
2020. Sample #1 (of NYC citizens) contained 24 subjects
(n1=24), the mean number of hours spent outside was
M1=40, and the sample’s variance was...

A physiological psychologist wanted to know if there is a gender
difference in consuming a sweet taste in rats. Ten male and ten
female rats were allowed to lick on a tube of saccharin-sweetened
water for ten minutes. The number of licks were 12, 11, 8, 9, 14,
10, 8, 9, 11, and 12 for the female rats and 6,7, 9, 5, 7, 9, 7, 8,
9, and 10 for the male rats.

A researcher wanted to know if there was a difference in the
effectiveness training results between permanent employees at a
business and temporary employees at the same business. The two
training methods were in-person training or via videos. After the
training, each employee took a test to determine the effectiveness
of the training. Draw the correct design for this experiment.
(Hint: In the design, it is easier to start off with the training
methodology.) Remember to clearly indicate what is...
