Researchers wondered if there was a difference between males and females in regard to some common annoyances. They asked a random sample of males and females, the followingquestion: "Are you annoyed by people who repeatedly check their mobile phones while having an in-person conversation?" Among the 505 males surveyed, 171 responded "Yes"; among the522 females surveyed, 202 responded "Yes." Does the evidence suggest a higher proportion of females are annoyed by this behavior? Complete parts (a) through (g) below.C-0.0484ő00.0484(e) Determine the P-value based on the model from part (d).First find the test statistic for this hypothesis test.(Round to two decimal places as needed.)

A television show conducted an experiment to study what happens when buttered toast is dropped on the floor. When 51 buttered slices of toast were dropped, 33 of them landed with the buttered side up and 18 landed with the buttered side down. Use a 0.01 significance level to test the claim that toast will land with the buttered side down 50% of the time. Use the P-value method. Use the normal distribution as an approximation to the binomial distribution. After that, supposing the intent of the experiment was to assess the claim that toast will land with the buttered side down more than 50% of the time, write a conclusion that addresses the intent of the experiment.
