Dr. Ahmed wants to study the relationship between blood pressure and heartbeat irregularities in his patients from the past weeks. He tests a random sample of his patients and notes their blood pressures (high, low, or normal) and their heartbeats (regular or irregular). He finds that: (i) 31% have high blood (ii) 39% have low blood pressure. (iii) 30% have an irregular heartbeat. (iv) Of those with an irregular heartbeat, one-third have high blood pressure. (v) Of those with normal blood pressure, one-fifth have an irregular heartbeat. pressure. a. What is the percentage of the patients selected have a regular heartbeat and low blood pressure? b. What is the percentage of the patients selected have an irregular heartbeat and normal blood pressure?

What is an experiment?
A statistician wants to determine if there is a difference in the fuel efficiency of cars between model years. To do this, he selects random makes and models of cars and compares the fuel efficiency in miles per gallon of the current model year and the previous model year. Suppose that data were collected for a random sample of 9 cars, where each difference is calculated by subtracting the fuel efficiency in miles per gallon of the previous model year from the fuel efficiency in miles per gallon of the current model year. Assume that the fuel efficiencies are normally distributed. What type of test is this hypothesis test? A. This is a two-tailed test because the alternative hypothesis is Ha:μd≠0. B. This is a right-tailed test because the alternative hypothesis is Ha:μd>0. C. This is a right-tailed test because the alternative hypothesis is Ha:μd<0. D. This is a left-tailed test because the alternative hypothesis is Ha:μd<0. E. This is a left-tailed…
What are the requirements for an experiment to be able to show that changes in one variable cause changes in another?
A researcher is comparing the occurrence of nausea as a side-effect in two brands of medication: Brand A and Brand B. For a random sample of 150 Brand A users, 66 experienced nausea as a side-effect. For a random sample of 200 Brand B users, 118 experienced nausea as a side-effect. Can the researcher conclude that the proportion of all Brand A users who experience nausea as a side-effect is different from the proportion of all Brand B users who experience nausea as a side-effect. For the hypothesis testing scenario above, the researcher concludes that the two proportions are different at the 0.01 significance level. Compute the 99% confidence interval to estimate the difference.
If the correlation between two quantitative variables becomes stronger and closer to 1, then we have stronger evidence that there is a causative relationship between the two variables. TRUE or FALSE?
In the past decades, there have been intensive antismoking campaigns sponsored by both federal and private agencies. In one study of national smoking trends, two random samples of U.S. adults were selected in different years. The first sample, taken in 1995, involved 4302 adults, of which 1642 were smokers. The second sample, taken in 2010, involved 3908 adults, of which 1415 were smokers. The samples are to be compared to determine whether the proportion of U.S. adults that smokes declined during the 15-year period between the samples. Let p1 be the proportion of all U.S. adults that smoked in 1995. Let p2 denote the proportion of all U.S. adults that smoked in 2010. The value of the z statistic for testing equality of the proportion of smokers in 1995 and 2010 is: Answer:
Hello, How do i solve for the value of the correlation coefficient?
A statistician for an automotive review magazine wants to determine whether there is a difference in the fuel efficiency of passenger vehicles between model years 2013 and 2018. To do this, he selects random makes and models of passenger vehicles and compares the fuel efficiency in miles per gallon of the 2018 model year and the 2013 model year. Suppose that data were collected for a random sample of 9 passenger vehicles, where each difference is calculated by subtracting the fuel efficiency in miles per gallon of the 2013 model year from the fuel efficiency in miles per gallon of the 2018 model year. Assume that the fuel efficiencies are normally distributed. The test statistic is t≈6.163, α=0.10, the corresponding rejection regions are t<−1.860 and t>1.860, the null hypothesis is H0:μd=0, and the alternative hypothesis is Ha:μd≠0. Which of the following statements are accurate for this hypothesis test in order to evaluate the claim that the true mean difference between the fuel…

A doctor is concerned about the relationship between blood pressure and irregular heartbeats.Among her patients, she classifies blood pressures as high, normal, or low and heartbeats asregular or irregular and finds that:• 16% have high blood pressure;• 19% have low blood pressure; • 17% have an irregular heartbeat;• of those with an irregular heartbeat, 35% have high blood pressure; and• of those with normal blood pressure, 11% have an irregular heartbeat.What percentage of her patients have a regular heartbeat and low blood pressure?
