Therapeutic touch (TT) practitioners claim to perceive an energy field above a patient's skin. To test this claim a TT practitioner was blind-folded and the researcher placed her hand over either the right or left hand of the practitioner. Let p denote the probability of a correct prediction by a TT practitioner. An experiment used 10 TT practitioners who had to predict the correct hand in each of 12 trials. Complete parts a through e. a. Define the parameter of interest and set up hypotheses to test that the probability of a correct guess is 0.50 against the TT practitioners' claim that it exceeds 0.50. Define a parameter of interest. Choose the correct answer below. OA. μ=average number of correct guesses B. p=probability of a correct guess O c. o=standard deviation of correct guesses Set up the hypotheses for the hypothesis test. Ho: P 0.5 Ha: p 0.5 (Type integers or decimals. Do not round.) b. The 120 trials had 66 correct guesses. Find and interpret the test statistic. Select the…
Anyone who has been outdoors on a summer evening has probably heard crickets. Did you know that it is possible to use the cricket as a thermometer? Crickets tend to chirp more frequently as temperatures increase. This phenomenon was studied in detail by George W. Pierce, a physics professor at Harvard. In the following data, x is a random variable representing chirps per second and y is a random variable representing temperature (°F). 21.0 15.1 19.0 17.6 17.5 15.5 14.7 17.1 y 87.8 71.4 94.1 84.7 81.4 75.2 69.7 82.0 15.4 16.2 15.0 17.2 16.0 17.0 14.4 69.4 83.3 79.6 82.6 80.6 83.5 76.3 Find x, and y. Then find the equation of the least-squares line ŷ = a + bx. (Round your answer to four decimal places.) %3D X = y = + %3D Find the value of the coefficient of determination r. What percentage of the variation in y can be explained by the corresponding variation in x and the least-squares line? What percentage is unexplained? (Round your answer for r² to four decimal places. Round your…

Tina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.

Manufacture of a certain component requires three different machining operations. Machining time for each operation has a normal distribution, and the three times are independent of one another. The mean values are 15, 20, and 30 min, respectively, and the standard deviations are 1, 2, and 1.4 min, respectively. What is the probability that it takes at most 1 hour of machining time to produce a randomly selected component? (Round your answer to four decimal places.)You may need to use the appropriate table in the Appendix of Tables to answer this question.
The following table shows the results of a medical test. Positive Test Result Negative Test Result 95.3 4.6 Total 82.6 % 4.6 Has Disease X % 491 24 % 515 Does Not Have Disease 45 Use the preceding data to estimate each of the following. (Express each response as a percentage rounded to one decimal place.) a. If a person has the disease, what is the probability that person tests positive? This is the sensitivity or true positive rate of a test. 214 259 Total b. If a person has the disease, what is the probability that person tests negative? This is sometimes called the false negative rate. 536 238 774 c. If a person does not have the disease, what is the probability that person tests negative? This is the specificity or true negative rate of a test. d. If a person does not have the disease, what is the probability that person tests positive? This is sometimes called the false positive rate. X %
Someone claims to have developed a new lightbulb whose mean lifetime is 1800 hours with a standard deviation of 100 hours. Consider these to be your population parameters. One of these types of bulbs was selected at random. What is the probability that it will have a lifetime of less than 1770 hours? Question 5 options: The probability is 0.3821, or 38.21% The probability is -0.3000, or -30.00% The probability is 0.3000, or 30.00% The probability is 0.6179, or 61.79%
