Find the critical value z subscript alpha divided by 2 that corresponds to the given confidence level. 93%

Step-by-step explanation:

We are asked to compute that corresponds to confidence level of 93%.

Now, we will use normal distribution table to find the z-score that corresponds to area of 0.035.

Therefore, the value of is .

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
