Answer:
Decision rule: Do not reject ; we cannot conclude that the mean differs from zero
Step-by-step explanation:
From the given information:
The null hypothesis and alternative hypothesis is given as:
And the 99% confidence interval for the population mean is: [−3.79, 5.86]
The significance level ∝ = 1 - 0.99 = 0.01
We will notice that the 99% confidence interval for the population mean contains the null hypothesis mean value which is equal to zero.
Thus, we do not reject the null hypothesis at the significance level ∝ = 0.01
∴
Decision rule: Do not reject ; we cannot conclude that the mean differs from zero
The answer is the last graph
Answer:
y=-x/4+4
Step-by-step explanation:
Slope intercept form: y=mx+b
x+4y=16
4y=-x+16
y=-x/4+4
The only pair of consecutive integers that
adds to -15 is -7 and -8 .
( -7 ) x ( - 8 ) = + 56 .
