Hi maam/Sir. I hope the tutor who will answer this is different from the one who answer last night because Im going to Compare both answers... my question last night was the same with this one

1. Measurements are made on a random sample of 23 components drawn from a population size of 100. Assume that the population is normal and the mean measurements of the components in the sample are 67.45mm with standard deviation of 2.93 mm. Determine a 95% confidence interval for an estimate of the mean of the population. a. 66.183u>68.717 C. 68.324>u>66.547 d. 68.324(>27.320 C. 23.435 > 24.565 13. The mean of the masses of random samples of 21 blocks is 24 kg with a standard deviation of 1.50 kg. Determine a 90% confidence interval for estimating the mean mass of the population. a. 23.9626
