In the upcoming election the most recent poll, based on 750 respondents, predicts that the incumbent will be reelected with 62 percent of the votes. From the 750 respondents, how many indicated that they would not vote for the current Student Body President or indicated that they were undecided?

In a research study investigated differences between male and female students. Based on the study results, we can assume the population mean and standard deviation for the GPA of male students are μ = 4.0 and σ = .75. Suppose a random sample of 100 male students is selected and the GPA for each student is calculated. Find the interval that contains 95.44 percent of the sample means for male students. μ = Population Mean σ =Population Standard Deviation [2.5, 5.5]
