The high temperature (in degrees Fahrenheit), x, and the ice cream sales (in dollars) for a local store, y, are related by the regression line equation y = -392.966 + 8.791x. Find the amount of sales predicted by the model if the high temperature is x = 94°F. Give your answer as a monetary amount rounded to the nearest cent.

Expert Solution

y = -392.966 + 8.791x

x = 94

y = -392.966 + 8.791 * 94 = $433.39 (ans)

The temperature X in degrees Fahrenheit (F) of a particular chemical reaction is known to be distributed between 220 and 280 degrees with a probability density function of fX(x) = (x − 190)/3600. A value of X degrees Fahrenheit can be converted to Y degrees Celsius (C) by taking Y = (5/9)(X − 32). Determine the following in both degrees F and degrees C: (a) the mean of the distribution (b) the variance of the distribution (c) the cumulative distribution...

An ice-cream producer’s sales are affected by the maximum daily temperature (typically, more sales when it is hotter). In summer the maximum daily temperature (in degrees Celsius) has a normal distribution with a mean of 31 and a variance of 25. The probability that the average maximum daily temperature on 18 randomly selected summer days is higher than 29 degrees is (to two decimal places)

An ice cream company collected data on their ice cream cones sales over a month in July in a Chicago suburb, along with daily temperature and the weather. The company is interested to develop a correlation between ice cream sales to the hot weather. Market research showed that more people come out in certain neighborhoods, to either enjoy the nice weather, or venture out if they do not have air conditioning in their apartments. The Chicago Police also tracked crime...
