The mean incubation time for a type of fertilized egg kept at a certain temperature is 25 days. Suppose that the incubation times are approximately normally distributed with a standard deviation of 1 day. Complete parts (a) through(e) below.

(a) Draw a normal model that describes egg incubation times of these fertilized eggs.

(b) Find and interpret the probability that a randomly selected fertilized egg hatches in less than 23 days.

The probability that a randomly selected fertilized egg hatches in less than 23 days is _?__. (Round to four decimal places asneeded.)

Interpret this probability. Select the correct choice below and fill in the answer box to complete your choice.

A. In every group of 100 fertilized eggs, __?__ eggs will hatch in less than 23 days. (Round to the nearest integer as needed.)

B. The average proportion of the way to hatching of all eggs fertilized in the past 23 days is _?__ (round to two decimal places as needed.)

C. If 100 fertilized eggs were randomly selected, _?__ of them would be expected to take more than 27 days to hatch. (round to the nearest integer as needed.)

(d) Find and interpret the probability that a randomly selected fertilized egg hatches between 24 and 25 days.

The probability that a randomly selected fertilized egg hatches between 24 and 25

days is __?__. (Round to four decimal places as needed.)

Interpret this probability. Select the correct choice below and fill in the answer box to complete your choice.

A. In every group of 100 fertilized eggs, __?__ eggs will hatch between 24 and 25 days. (Round to the nearest integer as needed)

B. If 100 fertilized eggs were randomly selected, _?__ of them would be expected to hatch between 24 and 25. (Round to the nearest integer as needed.)

C. The average proportion of the way to hatching of all eggs fertilized between 24 and 25 days is __?_. (Round to two decimal places as needed.)

(e) Would it be unusual for an egg to hatch in less than 22 days? Why?

The probability of an egg hatching in less than 22 days is __?_, so it : __would or would not_? be unusual, since the probability is: _less or greater ?_ than 0.05. (Round to four decimal places as needed.)

(20 points) a bank has been receiving complaints from real estate agents that their customers have been waiting too long for mortgage confirmations. the bank prides itself on its mortgage application process and decides to investigate the claims. the bank manager takes a random sample of 20 customers whose mortgage applications have been processed in the last 6 months and finds the following wait times (in days): 5, 7, 22, 4, 12, 9, 9, 14, 3, 6, 5, 15, 10, 17, 12, 10, 9, 4, 10, 13 assume that the random variable x measures the number of days a customer waits for mortgage processing at this bank, and assume that x is normally distributed. 2a. find the sample mean of this data (x ě…). 2b. find the sample variance of x. find the variance of x ě…. for (c), (d), and (e), use the appropriate t-distribution 2c. find the 90% confidence interval for the population mean (îľ). 2d. test the hypothesis that îľ is equal to 7 at the 95% confidence level. (should you do a one-tailed or two-tailed test here? ) 2e. what is the approximate p-value of this hypothesis?
