Edvin studies a species of mosquitoes called Aedes albopictus. As a part of the study, he collects information about the length of each specimen in the group he is studying. Here is a summary of the results:

Male Female

Mean 5.1 mm 6.3 mm

Standard deviation 1 mm 1.2 mm

Number of specimens 206 211

Edvin wants to use these results to carry out a two-sample t test to determine if the mean lengths are significantly different between males and females. Assume that all conditions have been met.

Which of the following would be an appropriate test statistic for Edvin's test?

Edvin Studies A Species Of Mosquitoes Called Aedes Albopictus. As A Part Of The Study, He Collects Information

Answers

Answer 1

The option that would be an appropriate test statistic for Edvin's test is A.

How to explain the information

Using the given information, we can calculate:

x1 = 5.1 mm, x2 = 6.3 mm

n1 = 206, n2 = 211

s1 = 1 mm, s2 = 1.2 mm

It should be noted that to calculate the pooled variance:

s²p = [((206-1)(1)^2 + (211-1)(1.2)^2) / (206+211-2)]

= 1.1 mm²

Plugging in the values, we get:

t = (5.1 - 6.3) / [ 1.1 * (1/206 + 1/211) ]^(1/2)

= -10.14

Therefore, the appropriate test statistic for Edvin's test is t = -10.14.
