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.

option 1

data plot with   3 dots over 33, 1 dot over 34, 2 dots over 35, no dot over 36, 1 dot over 37, 2 dots over 38, 4 dots over 39, and 2 dot over 40.

the probability is 0
