Use the following information to determine your The length of a movie falls on a normal distribution. About 95% of movies fall between 75 minutes and 163 minutes.

What is the value of the standard deviation for average movie length in minutes? Please round to the second decimal place.

And tha's equivalent to use this formula:

Step-by-step explanation:

For this case the 95%of the values are between the following two values:

(75 , 163)

And for this case we know that the variable of interest X "length of a movie" follows a normal distribution:

We can estimate the true mean with the following formula:

Now we know that in the normal standard distribution we know that we have 95% of the values between 1.96 deviations from the mean. We can find the value of the deviation with this formula:

And tha's equivalent to use this formula:
