Use the following information to find the test statistic of the sample used to test the claim that fico credit scores are greater than 675. n = 50, = 719, s = 92
t = 32.437

t = –32.437

t = –3.382

t = 3.382

t = –3.382

Step-by-step explanation:

Claim: FICO credit scores are greater than 675

Thus, x = 675

We are given:

Sample size = n = 50

Sample Mean = u = 719

Sample Standard deviation = s = 92

The formula to find the t-statistic is:

Using the above values, we get:

Thus, the value of test statistic is -3.382. So 3rd option gives the correct answer.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
