According to 2020 data, the average Facebook user has about 300 friends, and Facebook is the most popular social network among college students. The company has decided to start an advertising campaign if they get conclusive evidence that the average number of Facebook friends among college students is over 300. The company randomly selected a sample of 81 Ontario college students. For this sample group, the mean is 311 and the standard deviation is 45. Suppose that the distribution of number of Facebook friends is symmetric and approximately bell-shaped. Use a 0.050 level of significance to test the claim that the average number of Facebook friends among college students is over 300. Based on the result, should the company start the advertising campaign? Round to 3 decimal places where appropriate. (a) State the null and alternative hypotheses, and identify which one is the claim.

(b) What is the critical t-value? | 1.572 (c) What is the test statistic? (d) is the null hypothesis rejected? Is the alternative hypothesis supported?

Yes, the company should start the advertising campaign as we prove H1. At a 0.050 level of significance, the sample data support the claim that the average number of Facebook friends among college students is over 300. The company should start the advertising campaign. No, the company should not start the advertising campaign as 300 is less than 311. No, the company should not start the advertising campaign as we prove Ho. Yes, the company should start the advertising campaign as 300 is greater than 311. At a 0.050 level of significance, there is not sufficient sample evidence that the average number of Facebook friends among college students is over 300. Based on the research, we cannot conclude that the company should start the advertising campaign. Question Help: Message instructor Add Work Check Answer FI 20 800 F2 F3 14 F4 F5 F6 F7 F8 $ % &amp
