Question

One of the important features of a camera is the battery life as measured by the number of shots taken until the battery needs to be recharged. The data shown in the table below contain the battery life of 10 subcompact and 10 compact cameras.

Subcompact:

44, 47

26, 25

32, 35

33, 53

47, 58

Compact:

64, 25

55, 37

53, 32

52, 43

57, 68

Assuming that the population variances from both types of digital cameras are? equal, is there evidence of a difference in the mean battery life between the two types of? cameras? Use alpha = 0.02.

Determine the hypotheses. Which of the following is the correct answer?

A H sub 0 : ? sub 1 is greater than or equal to ? sub 2

H sub 1 : ? sub 1 < ? sub 2

B H sub 0 : ? sub 1 is less than or equal to ? sub 2

H sub 1 : ? sub 1 > ? sub 2

C H sub 0 : ? sub 1 = ? sub 2

H sub 1 : ? sub 1 isn't equal to ? sub 2

D H sub 0 : ? sub 1 isn't equal to ? sub 2

H sub 1: ? sub 1 = ? sub 2

Explanation / Answer

Option C is Correct

H sub 0 : ? sub 1 = ? sub 2

H sub 1 : ? sub 1 isn't equal to ? sub 2
