x 160 227 140 144 161 147 141
y 139 157 120 127 123 126 101

a. ^y=0.467+52.8x
b. ^y=2.29+0.0159x
c. ^y=0.0159+2.29x
d. ^y=52.8+0.467x

Determine the mean and variance of the random variable with the following probability mass function. f(x)=( 729divided by 91) (1 divided by 9) superscript x baseline comma x equals 1,2,3 round your answers to three decimal places (e.g. 98.765).
