Considering the situation described, the null hypothesis is given as follows:
.
<h3>What are the hypothesis tested?</h3>
At the null hypothesis, it is tested if the <u>mean is the same as in the Census</u>, of $64,000, hence:
.
At the alternative hypothesis, it is tested if the mean is different from the Census, hence:
.

Answer:
Equation 8+4 12+4 16+4 M=8 B=20 Your welcome
Step-by-step explanation:
I read:
Farm Maid Yogurt : 6 g of fat in 13 cups
Dairy Delight Yogurt: 5 g of fat in 11 cups.
(This is what I read, which does not represent realistic numbers, likely decimals are missing).
(a) Farm Maid Yogurt
6 g/13 cups = 10 g/x cups
Cross multiply: 6x = 130 => x=130/6=21.67 cups.
(b)
Farm maid : 6 g/13 cups, 6/13 in 13/13 cups => 0.4615 g/cup
Dairy Delight : 5 g / 11 cups, 5/11 in 11/11 cups => 0.4545 g/cup
=> Dairy Delight Yogurt has slightly less fat.
(c) 9 cups of Dairy Delight
5 g / 11 cups = x g / 9 cups
Cross multiply
11x=5*9 g => x=5*9/11 g = 4.09 g
(d) 3 cups of Dairy Delight & 5 cups of Farm Maid.
5 g/ 11 cups = x g / 3 cups
Cross multiply
x=5*3/11 = 1.3636 g
5 cups of Farm Maid
6 g / 13 cups = y g / 5 cups
Cross multiply
y=6*5/13=2.3077 g
Total fat consumed = 1.3636+2.3077 g = 3.6713 = 3.671 g (to the nearest thousandth gram).
Answer: option B
Step-by-step explanation:
Suppose you take a measure for each 5 seconds in a given observation, and the thing you are observing seems to change in the same amount in each meassure. This may mean that you are observing a linear relationship of the form y = a*x + b
Then, the simpler way to study this data set is by fiting with a linear equation.
