Agroup of 50 new york psychology students got a mean score of 530 on the psychology gre with a standard deviation of 80. these students claim to be way more nerdy than a group of 50 california psychology students who had a mean score of 515 with a standard deviation of 50. are the new york students truly more nerdy than the california students?

No, New York students are not truly more nerdy than the California students.

Step-by-step explanation:

Since we have given that

Number of students in a group = 50

Mean score of New York psychology = 530

Mean score of California psychology = 515

Standard deviation = 80

So, we will find t-distribution first.

Let α = 5% = 0.05

So,

Since t < t(critical value)

No, New York students are not truly more nerdy than the California students.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
