An article in the Journal of Sound and Vibration described a study on the relationshipbetween noise exposure and hypertension. The noise exposure is measured by theSound Pressure Level (SPL) whereas hypertension is measured by the Blood PressureRise (BPR). A representative data set reported is as follows:SPL60636570 707080 90 80 80 85 89 90ВPR15146354ySPL90 90 9094 100 100 100ВPR4y(a)Calculate sample mean, sample variances and sample covariance.(b)Write the fitted simple linear regression model for the above data.(c)Compute the coefficient of correlation.(d)Is it sufficient evidence to indicate that there is linear correlation between noiseexposure and hypertension?Predict the value ofhypertension when noise exposure is 75.6.2.6.7.1.5.

The toco toucan, the largest member of the toucan family, possesses the largest beak relative to body size of all birds. This exaggerated feature has received various interpretations, such as being a refined adaptation for feeding. However, the large surface area may also be an important mechanism for radiating heat (and hence cooling the bird) as outdoor temperature increases. Presented is the data for beak heat loss, as a percent of total body heat loss from all sources, at various temperatures in degrees Celsius.

Tourism is extremely important to the economy of Florida. Hotel occupancy is an often-reported measure of visitor volume and visitor activity (Orlando Sentinel). Hotel occupancy data for February in two consecutive years are as follows. Occupied Rooms Total Rooms Ho: P₁ P₂ #0 Ha: P1 - P2 = 0 Current Year Previous Year Ho: P1 - P2 = 0 Ha: P₁ P₂ #0 Ho: P₁ Ha: P₁ (a) Formulate the hypothesis test that can be used to determine if there has been an increase in the proportion of rooms occupied over the one-year period.
