Answer:
Hypotheses:
H0: There is no difference in the distribution of current sales.
H1: There is a difference in the distribution of current sales.
Enter the test statistic - round to 4 decimal places. 23.0951
Enter the p-value - round to 4 decimal places. 0.0003
Can it be concluded that there is a statistically significant difference in the distribution of sales?
Yes
please mark me brainliest!
Gonna be somewhere about 5 inches if I’m correct I hope this helps:)
Answer:
B. y = -0.58x^2 -0.43x +15.75
Step-by-step explanation:
The data has a shape roughly that of a parabola opening downward. So, you'll be looking for a 2nd-degree equation with a negative coefficient of x^2. There is only one of those, and its y-intercept (15.75) is in about the right place.
The second choice is appropriate.
_____
The other choices are ...
A. a parabola opening upward
C. an exponential function decaying toward zero on the right and tending toward infinity on the left
D. a line with negative slope (This might be a good linear regression model, but the 2nd-degree model is a better fit.)
To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y. If the equation is written in the slope-intercept form, plug in the slope and the x and y coordinates for a point on the line to solve y. Hope this helped! :)
