Due to the pandemic, Isabel has been unable to open up her make-up store and has instead been producing make-up tutorial videos, and she takes a survey of 56 random viewers to study their interaction. Isabel asks each of her viewers how much time they spend each week watching make-up tutorial.

a. What population did Isabel sample from?
b. What variable did she measure? Is it quantitative or qualitative?
c. Isabel's total audience contains about 12000 viewers. A brand she uses has agreed to sponsor her if her engagement exceeds 15000 hours per week. How many hours would that need to be PER viewer?
d. To assess whether her engagement is high enough for the sponsor mentioned in part c, what parameter should she use?
e. Using the parameter from part d and the individual engagement requirement from part c, what null hypothesis should Isabel write?
f. What is a suitable alternative hypothesis to go with the null hypothesis you wrote in part e.
g. Compute the appropriate P-Value for the hypotheses you wrote in parts e and f from the data provided.
h. Based on the P-Value from part g, and using a 0.10 significance level, does it appear that Isabel will meet the brand's engagement standard and get the sponsorship?
