The question and answers are in the screenshot.
A parent downloads an app that allows him to monitor the amount of screen time his child is using on the phone. The child claims that she is only using 1 hour per day on the phone on average, but the app, over the course of 47 days, finds that the child used an average of 1.2 hours per day. The parent wants to know if the child is using an average of 1 hour per day for all days of use. a) The 1.2 is a/an: variable population parameter sample statistic observational unit b) The sample size is: 1 47 1.2 c) Each day is a/an: population parameter observational unit variable sample statistic
V Several months ago while shopping, I was interviewed to see whether or not I'd be interested in signing up for a subscription to a yoga app. I fall into the category of people who have a membership at a local gym, and guessed that, like me, many people in that category would not be interested in the app. My friend Ivanna falls in the category of people who do not have a membership at a local gym, and I was thinking that she might like a subscription to the app. After being interviewed, I looked at the interviewer's results. Of the 98 people in my market category who had been interviewed, 17 said they would buy a subscription, and of the 120 people in Ivanna's market category, 26 said they would buy a subscription. Assuming that these data came from independent, random samples, can we conclude, at the 0.10 level of significance, that the proportion p₁ of all mall shoppers in my market category who would buy a subscription is less than the proportion p, of all mall shoppers in Ivanna's…

Decide if you think the statement is reasonable and accurate in all cases. Provide an explanation.
Suppose that A E Mmxn(R) is a matrix of user ratings of various movies (on a scale of 1 to 5). Suppose we have computed the SVD of А, and decided to keep the 10 largest singular values as the most important determining factors for a user's choice of movie. Suppose also that a new user has joined the movie subscription service, and has rated some, but not all, of the movies. To predict how this new user will rate other movies (and thus, to determine which ones to recommend), all movies the user has not watched are assigned the average rating for that movie given by all users to form a new matrix A' E M(m+1)xn(R), and the rank-10 approximation of A' is computed from its SVD. The values in the approximation to A' are taken as the predicted ratings for the new user. Given this procedure, which of the following conclusions is most correct?

An outcome is represented by a string of the sort OEE (meaning an odd number on the first roll, an even number on second roll, and an even number on the third roll). The 8 outcomes are listed in the table below. Note that each outcome has the same probability. For each of the three events in the table, check the outcome(s) that are contained in the event.
