Question

What are the steps to solve a and b?

In a lottery, you bet on a s digit number between 0 0000 and 11 11 For a S1 bet, you win S 700 000 you are correct. The mean and Standard de ation of the probability distribution or he ottery nings are μ 07 hat cents and σ = 700.00. Joan figures that if she plays enough times every day, eventually she will strike it rich, by the aw of large numbers. Over he course of several years. She plays l milion times. Let x denote her average 70 winnings a. Find the mean and standard deviation of the sampling distribution of x b. About how likely is t that Joan's average winnings exceed S1、the amount she paid to play each time? Use the central limit theorem to find an approximate answer a. The mean isand the standard deviation is Type integers or decimals. Do not round.)
