A vertinarian, Dr Gary is looking at the relationship between the amount of consumption of a new product SweetBone (in cups) and the weight of dogs (in pounds). He was able to collect samples from a select amount of customers in Alhambra.
Weight | Consumption |
39 | 4 |
148 | 8 |
79 | 5 |
41 | 4 |
85 | 5 |
111 | 6 |
37 | 3 |
111 | 6 |
41 | 3 |
91 | 5 |
109 | 6 |
207 | 10 |
49 | 3 |
113 | 6 |
84 | 5 |
95 | 5 |
57 | 4 |
168 | 9 |
121 | 7 |
Find the following:
a) The regression model of this data set
b) What is the coefficient of determination? Interpret your result.
c) What is the predicted weight of a selected dog if it consumes 8 cups of the dog food per week
d) At level of significance of 1%, is there a relationship between the weight of dogs and consumption of the dog food
e) A certain breed of dog weighs 140pounds, what is the suggested amount of the dog treat it eats.
f) What is the correlation coefficient? Interpret your results.
a)
b)
c)
d)
Hence we have enough evidence to claim that there is significance linear relation ship between two variables.
we are allowed to solve one question only.
