Lucy recently asked the servers at her restaurant to only give straws to customers who request them. She thinks that about half of the customers will ask for straws but hopes that the rate will be less than half. She randomly selects 100 customers and finds that 43 of them ask for a straw. To determine if these data provide convincing evidence that the proportion of customers who will ask for a straw is less than 50%, 150 trials of a simulation are conducted. Lucy is testing the hypotheses: Ho: p = 50% and Hp<50%, where p= the true proportion of customers who will ask for a straw. Based on the results of the simulation, what is the estimate of the P-value of the test?

Question
Lucy recently asked the servers at her restaurant to only give straws to customers who request them. She thinks that about half
of the customers will ask for straws but hopes that the rate will be less than half. She randomly selects 100 customers and finds
that 43 of them ask for a straw. To determine if these data provide convincing evidence that the proportion of customers who
will ask for a straw is less than 50%, 150 trials of a simulation are conducted. Lucy is testing the hypotheses: Hp: p = 50% and
H p<50%, wherep = the true proportion of customers who will ask for a straw. Based on the results of the simulation, what
is the estimate of the P-value of the test?
