Question

The following table shows the hot dogs bought from a street vendor over the course of eight days ("Demand"). Also shown is the temperature for each day in degrees Celsius. Complete parts a and b below.

Temperature °C 21 12 23 19 8 11 18 22

Demand 48 30 36 42 17 25 41 35

a. Calculate the slope and y-intercept for the linear regression equation for these data. y=+x (Round to two decimal places as needed.)

b. Predict the demand for hot dogs on a day with a temperature of 10 degrees Upper C°C.

1. David is a street vendor who sells hot dogs in the city and
would like to develop a regression model to help him predict the
daily demand for his product in order to improve inventory control.
David believes that the three main factors affecting hot dog demand
for a particular day are his price per hot dog, the high
temperature during business hours that day, and whether the day
falls on a weekday or weekend (many of David’s customers...

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. Here are
data for beak heat loss, as a percent of total body heat loss from
all sources, at various temperatures...
