Answer:
The correct option is D.
Step-by-step explanation:
The general exponential regression equations is
.... (1)
where, a is initial value and b is growth factor.
Using graph calculator, we get
Put the value of a and b in equation (1), to find the exponential regression equation.
Substitute a=3.53 and b=4.37 in equation (1).
The exponential regression equations that best fits the data is .
Therefore the correct option is D.

answer:
The result has a statistical significance because from the results obtained from the sample of people whom followed vegetarian diet and the people whom followed non-vegetarian diet we can see the different effects on blood pressure.
The result has a practical significance because the large difference in mean values.
Step-by-step explanation:
Sample size = 85 followed a vegetarian diet
Period = 4 months,
Mean systolic blood pressure= 124 mmHg
Sample size = 75 followed non-vegetarian diet
Period = 4 months
Mean systolic Bp = 138 mmHg
Reasons/explanations
Given that p -value < 0.01 we will reject the null hypothesis
The result has a statistical significance because from the results obtained from the sample of people whom followed vegetarian diet and the people whom followed non-vegetarian diet we can see the different effects on blood pressure.
The result has a practical significance because the large difference in mean values.
