Answer:

y=3x-10

Step-by-step explanation:

For this, you would use the point slope formula, which is (y-y1)=m(x-x1). x1 and y1 are the coordinates from the ordered pair.

(y-y1)=m(x-x1)

(y-2)=3(x-4)

y-2=3x-12

y=3x-10

To check, you can plug the coordinates into the equation.

y=3x-10

(2)=3(4)-10

2=12-10

2=2

A dessert manufacturer wanted to know if adding a preservative to their cupcakes extended their shelf life before going stale. T

aliina [53]

Answer:

The correct option is C) The results were not statistically significant but were practically significant.

Step-by-step explanation:

Consider the provided information.

They found that the difference in these shelf lives had a p-value of 0.24. Assume an α of 0.05.

We reject the null hypothesis if p value is less than α.

We are fail to reject null hypothesis if p value is greater or equal to α.

Here p value is greater than 0.05.

So, we do not reject null hypothesis and conclude that result is not statistically significant. But, there is a practical difference between 3 days and 7 days.

Therefore, the correct option is C) The results were not statistically significant but were practically significant.
