1:10 O b A O "Q. * a E (19 For numbers 1 to 3: The thermal condition in a cave is critical for sustaining a bat population. A sudden change in the temperature is related to deaths of bats in hundreds. An attempt to measure the degree of association between the temperature (in °C) and death toll (number of deaths) was done using 20 caves with reported cases of massive death among bats. Assume that temperature and death toll are bivariate normal. Given below is the R software output: > cor.test(temp , death) Pearson's product-moment correlation data: temp and death t - -1.4403, df - 148, p-value - 0.1519 alternative hypothesis: true correlation is not equal to e 95 percent confidence interval: -0.27269325 0.04351158 sample estimates: cor -0.1175698

Lesson 14: Using Normal Distributions for Exper. Destry Orceu Rescarchers are tagging sharks using two different types of devices and want to know if the devices affect the heart rate of tho sharks. They tag one aroup of 8 sharks with a small device that collects a small amount of data and thoy tag another group of 8 sharks with a larger device that collects a large amount of data. They then measure the mean heart rate of the different groups and find that the difference in means is 2.5 beats per minute. Rescarchers run 1,000 simulations regrouping the data into 2 groups at random and record the differences in means…
A researcher was interested in whether head worn displays were better than tablet displays for assisting rst responders with their tasks. He had 17 paramedics use either a head worn display (n = 9) or a tablet display (n = 8) during a simulated medical emergency. Each paramedic’s subjective workload score was measured out of 20 (where 20 indicated the highest workload). The data did not conform to the assumptions of a parametric test. a. What is the rank sum for the Head worn display group? a. 80 b. 73 c. 71 d. 82 b. What is the WS? a. 71 b. 80 c. 73 d. 82 c.

Managers of an outdoor coffee stand in Coast City are examining the relationship between (hot) coffee sales and daily temperature, hoping to be able to predict a day's total coffee sales from the maximum temperature that day. The bivariate data values for the coffee sales (denoted by y, in dollars) and the maximum temperature (denoted by x, in degrees Fahrenheit) for each of randomly selected days during the past year are given below. These data are plotted in the scatter plot below. (a)For these data, temperature values that are less than the mean of the temperature values tend to be paired with coffee sales values that are ▼(Choose one) the mean of the coffee sales values. (b)According to the regression equation, for an increase of one degree in temperature, there is a corresponding ▼(Choose one) of 9.94 dollars in coffee sales. (c)From the regression equation, what is the predicted coffee sales value (in dollars) when the temperature is 74.6 degrees Fahrenheit? (Round your…
