Use the following to answer question 39: The average score of 100 students taking a statistics final was 70 with a standard deviation of 7. Assuming a normal distribution, what is the probability that students scored less than 60

The probability of students scored less than 60 = .0768

Step-by-step explanation:

Given -

Mean score = 70

standard deviation = 7

Let X be the score of students

the probability that students scored less than 60 =

 =

                  =     put[ Z= ]

                   =    using z table

                    =  .0768

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
