A local college newsletter reported that the average American college student spends one hour (60 minutes) on a social media website daily. But you wonder if there is a difference between males and females. Attached below is a sample of 60 users of the website (30 males and 30 females) and their recorded daily time spent on the website. Complete (a) and (b) below. Click the icon to view the sample times. a. Assuming that the variances in the population of times spent on the website per day are equal, is there evidence of a difference in the mean time spent on the website per day between males and females? (Use a 0.05 level of significance.) Let μ, be the mean daily time spent on the website for male college students and μ₂ be the mean daily time spent on the website for female college students. Determine the hypotheses. Choose the correct answer below. OA. Ho: H₁ H₂ H₁ H₁ H₂ OC. Ho: H₁ = H₂ H₁ H₁ H₂ OB. Ho: H₁ H2 H₁: Hy > H₂ OD. Ho: H₁ H₂ H₁: Hy
