Paul wants to compare whether the prices of tangerines in two supermarkets differ significantly. He has been noting down the daily prices for the last few days and has found the difference in the sample means to be 20 cents. If the standard deviation of the distribution of the difference between sample means is 28 cents and we are testing the null hypothesis at the 95% confidence level, which statement is true? The difference between the two means is significant at the 95% confidence level, so the null hypothesis must be rejected. The difference between the two means is not significant at the 95% confidence level, so the alternative hypothesis must be rejected. The difference between the two means is not significant at the 95% confidence level, so the null hypothesis must be rejected. The difference between the two means is not significant at the 95% confidence level, so the alternative hypothesis must be accepted. The difference between the two means is significant at the 95% confidence level, so the alternative hypothesis must be rejected.

WILL GIVE BRAIN PLEASE HELP ASAPA mother tracks the duration of her baby's three daily naps for a few weeks. The mean time, in minutes, and the standard deviation, SD, for each nap are recorded in the table below. 1st Nap 2nd Nap 3rd Nap MEAN 83 SD = 9 Mean = 52 SD = 6 Mean = 39 SD = 11 Use the information in the table to select the true statement. The 3rd nap is the least consistent in duration because its mean is the lowest. The 2nd nap is the least consistent in duration because its standard deviation is the lowest. The 1st nap is the least consistent in duration because its mean is the highest. The 3rd nap is the least consistent in duration because its standard deviation is the highest.
