use of e-cigs at her school is higher. Complete parts (a) through (c) below.
(a) Determine the null and alternative hypotheses.
Но
Н:
(Type integers or decimals. Do not round.)
(b) If the sample data indicate that the null hypothesis should not be rejected, state the conclusion of the high school counselor.
O A. There is sufficient evidence to conclude that the proportion of high school students exceeds 0.097 at this counselor's high school.
O B. There is not sufficient evidence to conclude that the proportion of high school students exceeds 0.097 at this counselor's high school.
O C. There is not sufficient evidence to conclude that the proportion of high school students stayed 0.097 at this counselor's high school.
O D. There is sufficient evidence to conclude that the proportion of high school students stayed 0.097 at this counselor's high school.
(c) Suppose, in fact, that the proportion of students at the counselor's high school who use electronic cigarettes is 0.249. Was a type I or type Il error committed?
O A. AType l error was committed because the sample evidence led the counselor to conclude the proportion of e-cig users was 0.097, when, in fact, the
proportion is higher.
