Answer:
$9.08
Step-by-step explanation:
(find the difference means to subtract the second term from the first.)
$20.90 - $11.82 = $9.08
Answer:
Q1: 44
Q2: 1/2
Step-by-step explanation:
for questions one 8 times 5 equals 40 and 8 time 1/2 is 4 so 40 plus 4 equals 44
for question two you substitute x with 3/4 and and you have to do 2/3 times 3/4 and you get 6/12 which will then be simplified to 1/2
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
(X1-X2) + (Y1-Y2)
both pairs of parentheses are squared. if that makes sense. ()2. the entire equation is underneath a square root.
if this helped good. if not I'm sorry I confused you further.
