Use the results from a survey of a simple random sample of 1095 adults. Among the 1095 ​respondents, ​67% rated themselves as above average drivers. We want to test the claim that 3/5 of adults rate themselves as above average drivers. Identify the actual number of respondents who rated themselves as above average drivers. a.a. Identify the actual number of respondents who rated themselves as above average drivers? b. Identify the sample proportion and use the symbol that represents it. c.For the hypothesis​ test, identify the value used for the population proportion and use the symbol that represents it.

A teacher surveyed the students in one of his algebra classes, asking how many hours they spend watching TV shows, movies, and videos on a weekday. Their responses are given. Complete parts (a) through (e) below. 10 3 4 2 35 0 2 1 5 2 4 2 1 0 1 2 3 743 3 4 b. One student wrote "3-9." What value would represent this response well? Include the value in the sample for parts (c) through (d). A good value to represent the range 3-9 is c. Construct a dotplot. Choose the correct graph below. OA.
