The mean incubation time of fertilized eggs is 23 days Suppose the incubation times are approximately normally distributed with a standard deviation of 1 day (4) Determine the 19th percentile for incubation fines (b) Determine the incubation times that make up the middle 95% of fertilized eggs days (b) The incubation Simes that make up the middle 95% of fertilized eggs are todays (Round to the nearest whole number as needed. Use ascending order) (a) The 190 percentle for incubation times is (Round to the nearest whole number as needed)
People were polled on how many books they read the previous year Initial survey results indicate that s 17.5 books Complete parts (a) through (d) below Click the icon to view a partial table of critical values COD (a) How many subjects are needed to estimate the mean number of books read the previous year within four books with 90% confidence? This 90% confidence level requires subjects (Round up to the nearest subject) (b) How many subjects are needed to estimate the mean number of books mad the previous year within two books with 90% confidence? This 90% confidence level requires subjects (Round up to the nearest subject) (c) What effect does doubling the required accuracy haveth the sample size? OA Doubling the required accuracy nearly halves the sample size OB Doubling the required accuracy nearly quarters the sample size OC. Doubling the required accuracy nearly quadruples the sample size OD. Doubling the required accuracy nearly doubles the sample size (d) How many sub s are needed to estimate the mean number of books read the previous year within four books with 99% confidence? This 99% confidence level requires subjects (Round up to the nearest subject)
