Even #’s ONLY

Show calculations

Example 1

What is the critical value from a sample of four observations in the numerator and seven in the denominator? Use a one-tailed test at the .01 significance level.

Example 2

A computer manufacturer plans to unveil a new and faster personal computer. The new machine is clearly faster but initial tests indicate there is more variation in the processing time. The processing time depends on the program being run, the amount of input data and the amount of output. A sample of 16 computer runs, covering a range of production jobs, showed that the standard deviation of the processing time was 22 (hundredths of a second) for the new machine and 12 (hundredths of a second) for the current machine. At the .05 significance level, can we conclude that there is more variation in the processing time of the new machine?

Example 3

A media firm conducted a study of the iPod listening habits of men and women. One facet of the study involved the mean listening time. It was discovered that the mean listening time for men was 35 minutes a day. The standard deviation of the sample of the 10 men studied was 10 minutes per day. The mean listening time for the 12 women studied was also 35 minutes, but the standard deviation of the sample was 12 minutes. At the .10 significance level, can we conclude that there is a difference in the variation in the listening habits for men and women?

Example 4

Three universities have decided to administer the same comprehensive examination on their students. From each institution, a random sample of undergraduate students have been selected and given the test. The following table shows the scores of the students from each university

University UpNorth	University @Middle	University DownSouth
56	62	94
85	97	72
65	91	93
86	82	78
93		54
		77

At the .01 significance level, test to see if there is any significant difference in the average scores of the students from the three universities.

Example 5

The Ahmadi Corporation wants to increase the productivity of its line workers. Four different programs have been suggested to help increase productivity. Twenty employees, making up a sample, have been randomly assigned to one of the four programs and their output for a day’s work has been recorded as shown below.

Program A	Program B	Program C	Program D
150	150	185	175
130	120	220	150
120	135	190	120
180	160	180	130
145	110	175	175

Is there any difference in the employees’ outputs assigned to the different programs using the 0.05 level of significance? Be sure to show the 5-step working procedure for hypothesis testing.

Example 6

Random samples of individuals from three different mahallah of IIUM were asked how much time they spend per day studying or doing work related to academic matters. The results (in minutes) for the three mahallah and a partial ANOVA table are shown below.

*Mahallah I*	*Mahallah II*	*Mahallah III*
260	178	211
280	190	190
240	220	250
260	240
300

Source of Variation	Sum of Squares	df	Mean Square	F
Treatment	9,552.92	?	?	?
Error	?	?	?
Total	15,874.92	?

a. Complete the missing entries (?) in the ANOVA table.

b. At 95% confidence, test to see if there is a significant difference in the averages of the three groups.
