Based on the results from the sample at the end of 6 months, it was determined that pobs=.555. A member of the management team reports the following: “Although there does appear to be evidence that our market share has decreased, we do not consider it to be significant evidence in favor of the claim that the population proportion is less than .60.” Which of the following values for a level of significance could she be using in order for her statement to be appropriate? SHOW ALL RELEVANT COMPUTATIONS REQUIRED TO ANSWER THIS QUESTION. If there is more than one value, then circle ALL values that would lead to this conclusion. NOTE: This question concerns the strength of the evidence found in a sample

A marketing agency selected a random sample of television viewers to test the claim that the proportion of viewers who watch a particular show is less than 0.20 at a level of significance of 0.05. The test yielded a p-value of 0.47. Assuming all conditions for inference were met, which of the following is the correct conclusion? a) At the level of significance of 0.05, the null hypothesis is not rejected. There is not convincing evidence to suggest the true...
