In a study of 809 randomly selected medical malpractice lawsuits, it was found that 509 of them were dropped or dismissed. Use a 0.01 significance level to test the claim that most medical malpractice lawsuits are dropped or dismissed. Identify the null and alternative hypotheses. The null hypothesis, Ho, is a statement that the value of a population parameter (such as proportion, p, mean, µ, or standard deviation, o) is equal to some claimed value. The alternative hypothesis, H,, is the statement that the parameter has a value that somehow differs from the null hypothesis and uses the inequalities , or #, corresponding to a left, right, or two-tailed test, respectively. 5
A 9-year-old girl did a science fair experiment in which she tested professional touch therapists to see if they could sense her energy field. She flipped a coin to select either her right hand or her left hand, and then she asked the therapists to identify the selected hand by placing their hand just under her hand without seeing it and without touching it. Among 284 trials, the touch therapists were correct 125 times. Use a 0.05 significance level to test the claim that touch therapists use a method equivalent to random guesses. Do the results suggest that touch therapists are effective? Identify the null and alternative hypotheses for this test.
Many years ago, the M&M Mars Company claimed 0.3 of all M&Ms were red, 0.25 were green, 0.2 were brown, 0.15 were yellow, and the rest were orange. To test the company’s claim, you select a bag of M&Ms from the store shelf at random. If the calculated value for the associated test statistic equals 8.43279 and the level of significance equals 0.10 is the company claim resonable or unresonable

Recently, a large academic medical center determined that 13 of 20 employees in a particular position were female, whereas 41% of the employees for this position in the general workforce were female. At the 0.01 level of significance, is there evidence that the proportion of females in this position at this medical center is different from what would be expected in the general workforce?

In a survey, 43% of the respondents stated that they talk to their pets on the telephone. A veterinarian believed this result to be too high, so he randomly selected 210 pet owners and discovered that 84 of them spoke to their pet on the telephone. Does the veterinarian have a right to be skeptical? Use the α = 0.05 level of significance. Because npo (1-Po) = 10, the sample size is (Round to one decimal place as needed.) 5% of the population size, and the sample satisfied. the requirements for testing the hypothesis
The first question in in the second picture gets a little cut off, it says "the test statistic for this is ___". Thank you!
