A sample of 20 fossil skeletons of an extinct species of bird has been collected.The mean length of the skulls in this sample is 6.2 cm and the standard deviationof the sample is 0.35cm. Assuming that such measurements are normallydistributed, find a 90% confidence interval for the population mean length of theskulls of this species of bird.You may want to use one of these:qt (p=0.10, df-19, lower.tail=FALSE)=1.327728qt (p=0.05, df-19, lower.tail=FALSE)=1.729133qnorm(0.10, mean=0, sd=1, lower.tail=FALSE) =1.281552qnorm(0.05,mean=0, sd=1, lower.tail=FALSE)=1.644854O(6.065, 6.335)(5.624, 6.776)(5.751, 6.649)(5.595, 6.805)

It takes an average of 12.7 minutes for blood to begin clotting after an injury. An EMT wants to see if the average will increase if the patient is immediately told the truth about the injury. The EMT randomly selected 46 injured patients to immediately tell the truth about the injury and noticed that they averaged 13.5 minutes for their blood to begin clotting after their injury. Their standard deviation was 1.77 minutes. What can be concluded at the the a = 0.10 level of significance? a. For this study, we should use t-test for a population mean b.
