In hypotheses testing there is always a possibility that the decision we make is wrong as we are making decisions based on problitities , therefore there is chance that we would two type of errors .Explain the differences between the different types of error by completing the following.Please fill in the blank spaces' (a) A occurs when a researcher in correctly rejects a true null hypotheses. (b A occurs when a researcher incorrectly accepts a false null hypotheses. (c) A is when a researcher fails to rejrct the null hypotheses (d) A means that you are reporting that your findings are signicant , when in fact they have occured by chance. (e)A is also hnown as a false posive. (f)A is also known as a false negative. (g)THis means that a is when a gulity person id not convicted. (h) A is when an innocent person is concicted.

When a new drug is created, the pharmaceutical company must subject it to testing before receiving the necessary permission from the Food and Drug Administration (FDA) to market the drug. Suppose the null hypothesis is “the drug is unsafe.” What is the Type II Error? To conclude the drug is safe when in, fact, it is unsafe. Not to conclude the drug is safe when, in fact, it is safe. To conclude the drug is safe when, in fact, it is safe. Not to conclude the drug is unsafe when, in fact, it is unsafe.

A local chess club claims that the length of time to play a game has a mean of 23 minutes or more. Write sentences describing type I and type II errors for a hypothesis test of this claim. A type I error will occur if the actual mean of the length of time to play a game is ▼ less than equal to less than or equal to greater than not equal to greater than or equal to 23 minutes, but you ▼ fail to reject reject the null hypothesis, ▼ Upper H 0 : mu less than 23H0: μ<23 Upper H 0 : mu equals 23H0: μ=23 Upper H 0 : mu not equals 23H0: μ≠23 Upper H 0 : mu less than or equals 23H0: μ≤23 Upper H 0 : mu greater than or equals 23H0: μ≥23 Upper H 0 : mu greater than 23H0: μ>23 .

The mayor of a town has proposed a plan for the construction of an adjoining bridge. A political study took a sample of 800 voters in the town and found that 70% 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 74%. Testing at the 0.02 level, is there enough evidence to support the strategist's claim? a)State the null and alternative hypotheses. b)Find the value of the test statistic. Round your answer to two decimal places. c)Specify if the test is one-tailed or two-tailed. d)Determine the P-value of the test statistic. Round your answer to four decimal places. e)Identify the value of the level of significance. f)Make the decision to reject or fail to reject the null hypothesis. g)State the conclusion of the hypothesis test
Previously, 11.2% of workers had a travel time to work of more than 60 minutes. An urban economist believes that the percentage has increased since then. She randomly selects 85 workers and finds that 11 of them have a travel time to work that is more than 60 minutes . Test the economist's belief at the a= 0.1 level of significance What are the null and alternative hypotheses? what are the null and alternative hypotheses? Because np0(1-p0)= < ? 10, Find the P-value.
A highly selective quiz show wants their participants to have an average score greater than 90. They want to be able to assert with 95% confidence that this is true in their advertising, and they routinely test to see if the score has dropped below 90.. Select the correct symbols to use in the null hypothesis for this hypothesis test. Ho: ___________, ____________ 90.
For 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?
A golf instructor claims that more than 70% of his students have improved their driving distance by at least 20 yards after viewing and applying the techniques described in his instructional video. If 138 out of 180 viewers say that their driving distance has improved by at least 20 yards, is the instructor's claim valid? Identify the null and alternative hypotheses for this scenario. Is the instructor's claim that "more than 70% of his students have improved their driving distance by at least 20 yards," valid? Your response should include your decision and conclusion in context of the scenario.
A juice drink filling machine, when in perfect adjustment, fills the bottles with 19 ounces of drink on an average. Any overfilling or underfilling results in the shutdown and readjustment of the machine. Which of the following is the correct set of hypotheses to determine whether or not the machine is properly adjusted?
Formulate the indicated conclusion in nontechnical terms. Be sure to address the original claim. The principal of a middle school claims that test scores of the seventh-graders at his school vary less than the test scores of the seventh-graders at a neighboring school, which have variation described by σ= 14.7. Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to reject the null hypothesis, state the conclusion in nontechnical terms. a) There is not sufficient evidence to support the claim that the standard deviation is greater than 14.7 b) There is sufficient evidence to support the claim that the standard deviation is less than 14.7 c) There is sufficient evidence to support the claim that the standard deviation is greater than 14.7 d) There is not sufficient evidence to support the claim that the standard deviation is less than 14.7
