A television show conducted an experiment to study what happens when buttered toast is dropped on the floor. When42 buttered slices of toast were dropped, 24 of them landed with the buttered side up and 18 landed with the butteredside down. Use a 0.01 significance level to test the claim that toast will land with the buttered side down 50% of thetime. 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 morethan 50% of the time, write a conclusion that addresses the intent of the experiment.Let p denote the population proportion of all buttered toast that will land with the buttered side down when dropped.Identify the null and alternative hypotheses to test the claim that buttered toast will land with the buttered side down50% of the time.Ho: PH₁: p(Type integers or decimals. Do not round.)

A poll of 1086 Americans showed that 47.1% of the respondents prefer to watch the news rather than read or listen to it. Use those results with a 0.01 significance level to test the claim that fewer than half of Americans prefer to watch the news rather than read or listen to it. Use the P-value method. Use the normal distribution as an approximation to the binomial distribution.
A poll of 1188 Americans showed that 46.8% of the respondents prefer to watch the news rather than read or listen to it. Use those results with a 0.10 significance level to test the claim that fewer than half of Americans prefer to watch the news rather than read or listen to it. Use the P-value method. Use the normal distribution as an approximation to the binomial distribution. Let p denote the population proportion of all Americans who prefer to watch the news rather than read or listen to it.

Weight of goods shipped in containers of a certain size is a normally distributed random variable. It is known that 78% of the containers have a net weight above 4.3 tons, and 83% of the containers have net weight below 5.9 tons. Find the mean and standard deviation of the net weight of the containers.
Customers of a restaurant have been complaining about food poisoning over the past week. A health professional was called to investigate. She tested a representative sample of the eggs and reported that 24% of the sample eggs tested positive for the salmonella bacterium. If a second health professional tests 66 eggs at random, what is the probability that exactly 14 test positive for salmonella? Use a normal distribution to approximate the answer and write it as a decimal rounded to the nearest hundredth.
Five percent of U.S. employees who are late for work blame oversleeping. You randomly select four U.S. employees who are late for work and ask them whether they blame oversleeping. The random variable represents the number of U.S. employees who are late for work and blame oversleeping. Find the mean of the binomial distribution. μ= (Round to the nearest hundredth as needed.)

Assume that the average score on a statistical test is 8.5 and the variance is 2. The test was on the lighter side and the score distribution was very skewed (left skewed). What probability distribution is it reasonable to assume that the average grade of 3 randomly selected students who take the exam follows? 1. Normal distribution with mean 8.5 and variance 2. 2. Normal distribution with an average of 8.5 and a variance of 2/3. 3. Poisson distribution with an average of 8.5 and a distribution of 8. 4. The probability distribution cannot be predicted from the information provided.
A researcher wanted to determine if carpeted or uncarpeted rooms contain more bacteria. The table shows the results for the number of bacteria per cubic foot for both types of rooms.
