Let X subscript 1 comma... comma X subscript 9 denote the Intelligence Quotient IQ) of a randomly selected individuals. Assume that IQs are normally distributed with mean 100 and variance 162. Let S squared be the sample variance. Then, c S squared tilde chi squared (d f ). Find the constant "c" and degrees of freedom "df" of the chi-squared distribution.

Step-by-step explanation:

Find attached the solution

step-by-step explanation:

from the graph attached below:

domain of graph is the value of x for which the given function profit function p(x) is defined.

(a) the domain represents the number of years for which the outlet will earn a profit.

range of profit function defines the lowest to highest value of profit earned.

(b) the range of this function is (0 , 160 ). for this function, the range represents the outlet's profit earned.

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1
