2.) in the w column write in on top and mi in the bottom like this

w_K_U

in_

mi_

then in the k column write 2 for in and 15 for mi

W_K_U

in_2_

mi_15_

then in the U column, you write 7 for in and x for mi

W_K_U

in_2_7

mi_15_x

then cross multiply:  2x = 15(7)

multiply 15 times 7 which is 105

2x=105

divide 2x by 2

x=105 

answer 105

Answer:

0.7969

Step-by-step explanation:

Given that: A sample of size n= 49 is obtained. The population mean  is m= 80 and the population standard deviation is s = 14.

The z score measures the number of standard deviation by which the raw sore is above or below the mean. It is given by the equation:

z=\frac{x-m}{\frac{s}{\sqrt{n} } }

For x = 78.3, the z score is:

z=\frac{x-m}{\frac{s}{\sqrt{n} } }=\frac{78.3-80}{\frac{14}{\sqrt{49} } } =-0.85

For x = 85.1, the z score is:

z=\frac{x-m}{\frac{s}{\sqrt{n} } }=\frac{85.1-80}{\frac{14}{\sqrt{49} } } =2.55

P(78.3<x<85.1) = P(-0.85<z<2.55) = P(z<2.55) - P(z<-0.85) = 0.9946 - 0.1977 = 0.7969
