It was found that 25% of community college students in the state of california do not complete their intro stats class (i. e., either withdraw mid-course or fail). in an effort to reduce the non-completion rate, a new hybrid course format (on-line materials + face- to-face instructions) was designed to replace the traditional course. to test its effectiveness, a random sample of 300 california community college students who took the intro stats course in the new format was chosen and it was found that 66 of them (22%) did not complete the course. do these data provide enough evidence to conclude that when the course is taught in the new format the non-completion rate is reduced? let p be the proportion of all community college students in the state of california who took intro stats in the new format and did not complete the course. skill: carry out the hypothesis test for the population proportion and draw conclusions in context. the p-value is this case is above 10%. which of the following is the appropriate conclusion at the 5% significance level? a. we cannot reject h0. the data do not provide enough evidence to conclude that the new course format reduces the non-completion rate. b. we cannot reject h0. the data do not provide enough evidence to conclude that the new course format reduces the non-completion rate.
