The expected value of the sample mean of the values obtained in these 300 tosses is 3.5

Given :

A fair six sided die is tossed 300 times

We have to find the expected value of the sample mean of the values obtained in these 300 tosses.

A dice have six sides:

In a fair dice every side has equal chance of occurrence,

Now the probability of presence of each side = 1/6

Now the expected value of the sample mean of the values obtained in these 300 tosses is given by:

E(x) = Σx P(x =x)

= 1*1/6 + 2*1/6 + 3*1/6 + 4*1/6 + 5*1/6 + 6*1/6

= 1/6 + 2/6 + 3/6 + 4/6 + 5/6 + 6/6

= 1/6 (1+2+3+4+5+6)

= 1/6 (21)

= 21/6

E(x) = 3.5

Hence, the expected value of the sample mean of the values obtained in these 300 tosses is 3.5

Number 6. I have no idea how to do this because the question doesn’t give enough information
Savatey [412]

{13}^{2}  =  {5}^{2}  \times {b}^{2}  \\ 169 = 25 \times  {b}^{2}  \\ 165 - 25 =  {b}^{2}  \\ 144 =  {b}^{2}  \\  \sqrt{ {b}^{2} }  =  \sqrt{144}  \\ b = 12
