Question

The business problem facing the director of broadcasting operations for a television station was the issue of standby hours and what factors were related to standby hours. The study included the following variables: Standby hours (Y) – Total number of standby hours in a week Weekly staff count (X1) – Weekly total of people-days Remote engineering hours (X2) – Total number of engineering hours worked by employees at locations away from the central plant Data were collected for 26 weeks. (See image attached) A)Interpret the meaning of the coefficients b1 and b2 in this problem B) What is the significance of b0? C) Predict the mean standby hours for a week in which the weekly staff count was 310 people-days and the remote-engineering hours total was 400

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
