In a two-way ANOVA, what are: 1) the sampling design (how is sampling accomplished ) 2) what is the recommended use of the design

The Tokyo Marine Consultant wants to conduct a survey with the aim is to estimate banking and hospital service time. For this reason, observations are made on the waiting time data of each customer for one period which is obtained from the two business sectors. The sample data was taken randomly from 11 customers separately and independently from bank and hospital customers. The following data are the waiting times from 22 samples ofcustomers.                                          Waiting Time (In minutes) Banking   9.66  5.9     8.02     5.79   8.73   3.82   8.01   8.35   10.1   6.6    5.6Hospital   4.21  5.55   3.02     5.13   4.77   2.34   3.54   3.2      4.5    6.1    0.3 a. Calculate the average and standard deviation of waiting time at banks and hospitals. b. Assuming the population variance is the same, determine the estimated limits of the difference between the average waiting time from the survey results from the survey with a significance level of 5%?c. Do the same thing…

1) Create a example of a scenario where a one-way ANOVA would be used in this  2) Give a example of a scenario where an ANOVA with repeated measures would be used in it

Why do all cells in two-factor studies should have equal sample sizes?
