The general manager of an engineering firm wants to know whether a technical artist’s experience influences the quality of his o
r her work. A random sample of 24 artists is selected and their years of work experience and quality rating (as assessed by their supervisors) recorded. Work experience (EXPER) is measured in years and quality rating (RATING) takes a value of 1 through 7, with 7 = excellent and 1 = poor. The simple regression model RATING =β1+β2EXPER+???? is proposed. The least squares estimates of the model, and the standard errors of the estimates, are
RATING = 3 204 + 0.076
EXPER (sc) (0.709) (0.044)
Sketch the estimated regression function with labeled axis.
Interpret the coefficient of EXPER.
RATING = 3 204 + 0.076

Answer:
Answer: The estimated equation is shown in the scattered plot diagram attached to the answer supplied
Step-by-step explanation:
(a) Attached scattered plot diagram
(b) Estimated regression equation:
Rating = 3.204 + 0.076 EXPER
b1= 3.204,
b2= 0.076
Se(b1)= 0.709
Se(b2) = 0.044
n=2
The coefficient of EXPER =0.076. This implies that the quality rating will increase by 0.076.

The longest line segment that can be drawn in a right rectangular prism that is 14cm long, 13cm wide and 11cm tall is 19.1cm.
<h3>What is a right rectangular prism?</h3>A right rectangular prism is a three dimensional solid shape formed by 6 rectangles.
it is also called the cuboid.
Analysis:
The diagonal of the face of the prism with dimensions 14cm long and 13cm wide is the longest line segment that can be drawn.
Since rectangles have 90° on each vertex, we can use Pythagoras theorem to calculate for the length of the diagonal.

= 196 + 169 = 365
= 365
diagonal = = 19.1cm
In conclusion, the length of the longest diameter is 19.1cm

Answer:
Initial height or what the ball was originally bounced from a height of 9 feet
Step-by-step explanation:
9 represents the height that the ball was originally bounced from.
If you plug in 0 for into
, you get:
.
9 feet is the initial height since that is what happens at time zero.
