Many people believe that the average number of Facebook friends is 125. The population standard deviation is 37.7. A random sample of 33 high school students in a particular county revealed that the average number of Facebook friends was 153. At a=0.10, is there sufficient evidence to conclude that the mean number of friends is greater than 125? a) State the hypotheses and identify the claim with the correct hypothesis. 01. Ho: s153 Not claim Hyp>153 claim O2 Ho P2125 claim H:<125 Not claim 3. Hows 125 Not claim Hyp>125 claim b) Find the critical value (s). O 1. CV=1.28 O2. CV-1.33 3.CV-1.96 c) Compute the test value: O 1.2=4.35 2. z=4.22 O 3. z= 4.27 d) Make the decision O 1. Reject the nuli hypothesis. 2. Do not reject the null hypothesis e) Summarize the results. 1. There is enough evidence to support the claim. 2.There is not enough evidence to support the claim.
