- For the one-sided alternative hypothesis β2 < 0 and 1% rejection rule (i.e., at the 1% level), would you reject, or accept, the null hypothesis that β2 = 0.Formulate a null and alternative hypothesis with the topic "the water quality of a river"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.
- If the null hypothesis states H0: E(Y) = , explain the difference between a two-sided vs a one-sided alternative hypothesis. Give an real-life example in each testFor the given scenario, determine the type of error that was made, if any. (Hint: Begin by determining the null and alternative hypotheses.) A pharmaceutical company claims only 2% as the percentage of people taking a particular drug that experience significant side effects. One researcher claims that the percentage of people taking a particular drug that experience significant side effects is less than 2%. The researcher conducts a hypothesis test and fails to reject the null hypothesis. Assume that in reality, the percentage of people taking a particular drug that experience significant side effects is 0.5%. Was an error made? If so, what type?Assume you are conducting a hypothesis test to determine if pesticides cause cancer in rural areas. The hypotheses are: The null hypothesis is no cancer. The alternate hypothesis is cancer. Select if the result for Box C is correct, a Type I error, a Type II error or if there is insufficient information to make the decision.

B) What kind of mistake would be made if the Ho that the dam is safe is wrongly accepted?the null and alternative hypothesisStudents who arrive to class early do just as well on the homework as those who arrive to class late.

- 2) Assume you are conducting a hypothesis test to determine if pesticides cause cancer in rural areas. The hypotheses are: The null hypothesis is no cancer. The alternate hypothesis is cancer. Select if the result for Box D is correct, a Type I error, a Type II error or if there is insufficient information to make the decision.The mayor of a town has proposed a plan for the construction of an adjoining bridge. A political study took a sample of 900 voters in the town and found that 48% of the residents favored construction. Using the data, a political strategist wants to test the claim that the percentage of residents who favor construction is not equal to 51%. Testing at the 0.05 level, is there enough evidence to support the strategist's claim? Step 1 of 6 : State the null and alternative hypotheses.You are testing the null hypothesis µ=55 versus the two tailed alternative. You fail to reject the null hypothesis. If in reality, µ does not equal 55, you have made a: Type II error Correct Decision Type I error
