Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correctsymbol (µ, p, Η) for the indicated parameter. An entomologist writes an article in a scientific journalwhich claims that fewer than 16 in ten thousand male fireflies are unable to produce light due to agenetic mutation. Use the parameter p, the true proportion of fireflies unable to produce light.
Suppose we have the following hypotheses: Ho:p=.64 H1:p>.64 What would it mean to make a Type Il error? O a. We conclude that p = .64 when it actually isn't. O b. We conclude that p = .64 and we are correct. O c. We conclude that p > .64 when it's actually smaller. O d. We conclude that p > .64 and we are correct.

This is because nausea is common for people who have the flu. From past studies you know that about 33% of people who get the flu experience nausea. You collected data on 2371 patients who were taking Tamiflu to relieve symtoms of the flu, and found that 841 experienced nausea. Use a 0.01 significance level to test the claim that the percentage of people who take Tamiflu for the relief of flu symtoms and experience nausea is greater than 33%. *.** ▸ Ezra Mill X HH Chief Be X V H₁: ?

For the given scenario, determine the type of error that was made, if any. (Hint: Begin by determining the null and alternative hypotheses.) Insurance companies commonly use 10001000 miles as the mean number of miles a car is driven per month. One insurance company claims that the mean number of miles a car is driven per month is more than 10001000 miles. The insurance company conducts a hypothesis test and fails to reject the null hypothesis. Assume that in reality, the mean number of miles a car is driven per month is 12001200 miles. Was an error made? If so, what type?
A study by researchers at a university addressed the question of whether the mean body temperature of an animal is 98.2°F.Among other data, the researchers obtained the body temperatures of 97 healthy animals. Suppose you want to use those data to decide whether the mean body temperature of healthy animals is greater than 98.2°F. Complete parts (a) through (c) below. a. Determine the null hypothesis. H0: μ ______ (=, >, < or ≠) ________ ________________ (healthy animals or °F) (Type an integer or a decimal. Do not round.) b. Determine the alternative hypothesis. Ha: μ (=, >, < or ≠) ________ ________________ (healthy animals or °F) (Type an integer or a decimal. Do not round.) c. Classify the hypothesis test as two tailed, left tailed, or right tailed. The hypothesis test is _______________ (right tailed, left tailed or two tailed)
