- The data for the height of women is approximately bell-shaped. If a woman’s height has a z-score of -1.3, what percentage of women is shorter than she is?For a z-score of Z = -2.2, give the proportion in the body (hint: use the z-table), and state whether the body is to the right or to the left of this z-score (hint: draw a picture).A researcher reports an F-ratio with df = 1, 24 for an independent-measures experiment. If all the treatments had the same number of participants, then how many individuals were in each treatment?
- Diastolic blood pressure in adults is normally distributed with m = 80 mm Hg and s = 12 mm Hg. In a ran-dom sample of 300 adults, how many would be expected to have a diastolic blood pressure below 70 mm Hg?An agronomist wanted to compare the yield of three different varieties of rice (A, B, C). So, within a field, he randomly assigned each variety to five plots. The yield[s] in pounds per acre were recorded for each plot. (f) Outline the design of the experiment.for a population with a µ = 60 and σ = 12 Find the z-score for an x value of 75
- A researcher thinks that watching violent televisions increases aggressive behavior in children. To test this hypothesis, she randomly assigns 48 children into one of 3 groups (no violent TV, a little violent TV, or a lot of violent TV) and observes their playground behavior for three weeks and measures it for violence and intensity. For the variable “amount of TV” (as it appears in this problem), what is the scale of measurement? a. nominal b. ordinal c. interval d. ratio A researcher thinks that watching violent televisions increases aggressive behavior in children. To test this hypothesis, she randomly assigns 48 children into one of 3 groups (no violent TV, a little violent TV, or a lot of violent TV) and observes their playground behavior for three weeks and measures it for violence and intensity. If the researcher’s hypothesis is correct, which of the following conclusions could be drawn? a. Fail to reject the null, watching violent TV does not increase…Researchers conducted a survey among 400 doctors to ask the question; "Are you willing to treat your patients with a new experimental drug?" The approximate margin of error here is:Given a 95% C.I. = (34.14 mm, 36.02 mm) for a sample of Wooly Bear caterpillar lengths, determine the Maximum Error of the Estimate (aka margin of error), E, for this interval.
