To test the hypothesis that the population mean mu=10.8, a sample size $n=5$ yields a sample mean $12.270$ and sample standard deviation $1.233$. Calculate the $P$. value and choose the correct conclusion. Your answer: The P-value $0.018$ is not significant and so does not strongly suggest that mu>10.8. The P-value $0.018$ is significant and so strongly suggests that mu>10.8. The P.value $0.028$ is not significant and so does not strongly suggest that mus $10.8$. The Pvalue $0.028$ is significant and so strongly suggests that mu>10.8. The P-value $0.014$ is not significant and so does not strongly suggest that mu> $10.8$. The P.value $0.014$ is significant and so strongly suggests that mup $10.8$. The P-value $0.412$ is not significant and so does not strongly suggest that mu> $10.8$. The P-yalue $0.412$ is significant and so strongly suggests that mu>10.8. The P. value $0.344$ is not rignificant and so does not strongly suggest that mu> $10.8$. The P. Palue $0.344$ is significant and so strongly suggests that mus10.8.
To test the hypothesis that the population standard devation sigma-18.9, a sample size nu11 yields a sample standard deviation $14.701$, Calculate the p.value an choose the correct conclusion. Your answer: The P.yalue $0.015$ is not significant and so does notstrongly suggest that sigmac18.9. The P-value $0.015$ is significant and sorstrongly suggests that sigmac18.9. The Pvalue $0.002$ is not significan and so does not strongly suggest that sigma<18.9. The P.value $0.002$ is significant and so strongly suggests that signos18.9. The P.value $0.346$ is not rignificant and so does not strongly suggest that sigma<18.9. The P.value $0.346$ is significant and so strongly suggests that sigmac18.9. The P.value $0.189$ is notsignificant and so does not strongly suggest that sigma<18.9. The P.value $0.189$ is significant and so strongly segzests that sigmaz $18.9$. The P-value $0.008$ is not significant and so does not strongly suggest that sigma<18.9 The P.value $0.008$ is significant and so strongly suggests that siemisi8. 9
To tert the hypothesis that the population mean mu=8.1, a sample size $n=21$ yicids a sample mean $8.278$ and sample standard deviation $0.296$. Caiculate the $P$. value and choose the correct conclusion. Your answer: The P-value $0.361$ is not significant and so does not strongly suggest that $mu>8.1$. The Pryalue 0,361 is significant and 50 strongly suggests that mu>8.1. The P.value $0.026$ is not significant and so does not strongly suggest that mu>.1. The P-value $0.026$ is significant and so strongly suggests that mu>8,1. The Prvalue $0.351$ is not subnificant and so does not strongly suggest that mu>8.1. The pivalue $0.351is$ significant and so strongly suggests that mis.8.1. The P.value $0.018$ is not significant and so does not strongly sugsest that mup. 1 . The P.value $0.018$ is significant and so strongly sugeests that mu>8,t. The Prualue $0.006$ is not significant and so does not strongly suggest that muse. 1 . The Pratue $0.000$ is signsicint and so strongly sugeests that muse.1.
To test the hypothesis that the population standard deviation sigma 15.7, a sample size nu24 yieids a sample standard deviation $10.525$. Caiculate the P-value and choose the correct conclusion. Your answer: The P.value $0.011$ is not significant and so does not strongly sugsest that sigmac15.7. The P.value $0.011$ is significant and so strongly suggests that sigmac15.7. The P.value $0.346$ is not significant and so does not strongly suggest that sigmac15.7. The p.yalue $0.346$ is significant and so strongly suggests that sigma<15.7. The P.yalue $0.021$ is not significant and so does not strongly suggest that sigmac15.7. The Pvalue $0.027$ is significant and so strongly suggests that sigmact15.7. The P-value $0.005$ is not significant and so does not strongly suggest that sigmac15.7. The P.value $0.005$ is significant and so strongly suggests that stgmacts.7. The Pivalue $0.280$ is not signficant and so does not strongly suggest that sigmae15.7. The R-value $0.280$ is significant and so strongly susgests that sigmac15.7.
