Astudent wants to determine if pennies are really fair, meaning equally likely to land heads up or tails up. he flips a random sample of 50 pennies and finds that 28 of them land heads up. calculate the p-value and state the conclusion. use α = .05.

Pennies are not really fair.

Step-by-step explanation:

Given that a  student wants to determine if pennies are really fair, meaning equally likely to land heads up or tails up.

Let us do hypothesis test claiming p = 0.50

(two tailed test)

p = proportion of heads to total

Sample proportion P =

Std error =

Test statistic = p diff/std error

=

p value = 0

Since p is less than 0.05

reject H0.

It is statistically evident that the events are not equally likely for head or tail.

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 %
