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.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

f(x)=2/3x-8, which give g(x) the greatest value.
