5.3.2. The production of a nationally marketed deter- gent results in certain workers receiving prolonged expo- sures to a Bacillus subtilis enzyme. Nineteen workers were tested to determine the effects of those expo- sures, if any, on various respiratory functions. One such function, air-flow rate, is measured by computing the ratio of a person's forced expiratory volume (FEV,) to his or her vital capacity (VC). (Vital capacity is the maximum volume of air a person can exhale after taking as deep a breath as possible; FEV, is the max- imum volume of air a person can exhale in one sec- ond.) In persons with no lung dysfunction, the “norm" for FEV,/VC ratios is 0.80. Based on the following data (164), is it believable that exposure to the Bacillus sub- tilis enzyme has no effect on the FEV,/VC ratio? Answer the question by constructing a 95% confidence interval. Assume that FEV,/VC ratios are normally distributed with o =0.09.

The power of a study is 1 minus beta equal the probability that a researcher will reject H0when H0 is false. Can you tell me if this statement is True or False

Recently, Goran ran for president of the local school board. Of those who voted in the election, 80% had a high school diploma, and the other 20% did not. Goran got 70% of the vote of those with high school diplomas, while he got only 15% of the vote of those without high school diplomas. Let D denote the event that a randomly chosen voter (in the school board election) had a high school diploma and D denote the event that a randomly chosen voter did not have a high school diploma. Let V denote the event that a randomly chosen voter voted for Goran and V denote the event that a randomly chosen voter did not vote for Goran. Fill in the probabilities to complete the tree diagram below, and then answer the question that follows. Do not round any of your responses. (If necessary, consult a list of formulas.) (a) Fill in the missing probabilities. P(VD) = 0.7 P(DnV) = 0 P (D) = 0.8 Continue Submit Assignme Privacy Center | Accessibili (4¹) Ⓒ2022 McGraw Hill LLC. All Rights Reserved. Terms…

Question 7- Part A. If Alex has scored 510 on the MCAT, and was at the 75th percentile, and Boris has scored 520, and was at the 95th percentile, then approximately how much percent (%) of all the students who wrote MCAT had the score lower than Boris and higher than Alex? Provide answer in Percentage.
