An educational psychologist is examining response times Lo an on-screen stimulus. The researcher believes there might be a weak effect from age, but expects a more pronounced eflect for different color contrasts. She decides to examine ablack on white (BW) combination compared to 2 alternatives: red on white (R/W) and yellow on blue (Y/D).

For the following exercises, consider this scenario: The population of a city increased steadily over a ten-year span. Thefollowing ordered pairs shows the population (in hundreds) and the year overthe ten-year span, (population, year) forspecific recorded years: (4,500,2000);(4,700,2001);(5,200,2003);(5,800,2006) Predict when the population will hit 20,000.

Compare the two separate scatterplots. In particular, how do the associtation compare between women with pets vs. women without pets? Does one group have more variation in systolic blood pressure than the other? If so, for which group? Does systolic blood pressure seem higher for common ages between the two groups? If so, for which group?
Trenny has asked her assistant to prepare estimates of cost of two different sizes of power plants. The assistant reports that the cost of the 110 MW plant is $190,000,000, while the cost of the 210 MW plant is $380,000,000. If Trenny has a budget of only $300,000,000, estimate how large a power plant she could afford using linear interpolation (Enter your answer rounded to one decimal place and in MW eg. XX.X)?

A survey among the workers in a large manufacturing company was taken, in order to findout from which company the workers had purchased their mobile phones, and to find outwhether the choice of mobile phone company was related to the type of worker. The resultsare shown in the table below. ls there evidence, at 5% level, that the choice of Phone Company is independent of the type ofworker?
A researcher collects data that represents the average number of hours of sleep in the last two nights by 8 depressed patients and 9 non-depressed patients. The researcher is interested in whether the two groups reliably differ in the amount of sleep they get. Use Jamovi to calculate t-obt and the p value.
By accident, Janae has been making decaffeinated coffee for her co-workers for the entire week. But some of her co-workers have claimed that the extra boost of caffeine has helped them focus on their work.What does the placebo effect mean in this specific situation? a.) The benefit is the result of the "control" (coffee, although decaffeinated) and not an effect of the "active ingredient" (caffeine). b.) The benefit is the result of the fact that the "treatment" (coffee, although decaffeinated) contains another "active ingredient" besides caffeine. c.) The benefit is due to the fact that the co-workers are given a "treatment" (coffee, although decaffeinated) and not an effect of the "active ingredient" (caffeine). d.) The co-workers get a benefit from the "treatment" (coffee, although decaffeinated) since they also drink coffee at the coffee shop across the street during breaks.
