A television show conducted an experiment to study what happens when  buttered toast is dropped on the floor. When 47 buttered slices of toast were​ dropped, 26 of them landed with the buttered side up and 21 landed with the buttered side down. Use a .10 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.
