Homework SourseOne particular morning the length of time spent in the exami
One particular morning, the length of time spent in the examination rooms is recorded for each patient seen by each physician at an orthopedic clinic.
Fill in the missing data. (Round your p-value to 4 decimal places, mean values to 1 decimal place and other answers to 3 decimal places.)
Based on the given hypothesis, choose the correct option.
Calculate the F for one factor. (Round your answer to 2 decimal places.)
\"On the basis of the above findings, we reject the null hypothesis\". Is the statement true?

Solution
The table is given as follows,
To perform a single factor ANOVA Using excel.
EXCEL PROCEDURE
The Output is obatained as below,
(a) Based on the given hypothesis,
H0: The mean waiting times are the same for all the physicians.
Ha: The mean waiting times for at least one physician is different from the rest.
Since the calculated f- value (2.29) < F- critical (3.00), So accept H0 and reject Ha
Calculate the F for one factor.
From the Excel output the value of F for one factor is obtained as 2.29.
C) On the basis of the above findings reject or accept null hypothesis.
From the above findings the F-value is obtained as 2.29 and the p-value is 0.10.
Conclusion: Since the p-value is greater than 5%,fail to reject H0 .That is Accept the null hypothesis,the mean waiting times are the same for all the physicians.
Since the statement is not true that the null hypothesis is rejected.
