A random sample of 33 new homes indicated that the mean cost was $120.14 and the standard deviation was $16. Can it be concluded that the mean cost differs from 117.91, using the o.05 level of significance? a) State the hypotheses and identify the claim with the correct hypothesis. 01. Ho:p>$117.91 Not claim H1:u=$117.91 claim O2. Ho:p>$117.91 Not claim H1:p>$117.91 claim 03. Ho:u=$117.91 Not claim H:$117.91 claim
b) Find the critical value (s). 01. CV=+1.65 O 2. CV=+1.96 03. CV= -2.58 c) Compute the test value: 01. Z= -0.85 O 2. Z=0.89 O 3. Z= 0.80 d) Make the decision. 01. Reject the null hypothesis. 2. Do not reject the null hypothesis. e) Summarize the results. 01. There is enough evidence to support the claim. 2.There is not enough evidence to support the claim.
