Answer:
21.16
Step-by-step explanation:
Starting from the theory we have the following equation:
![fi*P(x](https://tex.z-dn.net/?f=fi%2AP%28x%3Cc-1%29%20%3D%200.99)
Using the data supplied in the exercise, we have subtracting the mean and dividing by the standard deviation:
![P( z \leq \frac{c-1-12}{3.5}) =0.99/fi](https://tex.z-dn.net/?f=P%28%20z%20%5Cleq%20%5Cfrac%7Bc-1-12%7D%7B3.5%7D%29%20%3D0.99%2Ffi)
solving for "c", knowing that fi is a tabulating value:
![\frac{c-13}{3.5}=0.99/fi\\\frac{c-13}{3.5}=2.33\\c-13=2.33*3.5\\c = 8.155 +13\\c = 21.155](https://tex.z-dn.net/?f=%5Cfrac%7Bc-13%7D%7B3.5%7D%3D0.99%2Ffi%5C%5C%5Cfrac%7Bc-13%7D%7B3.5%7D%3D2.33%5C%5Cc-13%3D2.33%2A3.5%5C%5Cc%20%3D%208.155%20%2B13%5C%5Cc%20%3D%2021.155)
therefore the value of c is equal to 21.16
