Answer:
The 90% confidence interval for the difference in mean (μ₁ - μ₂) for the two bakeries is; (<u>49</u>) < μ₁ - μ₂ < (<u>289)</u>
Step-by-step explanation:
The given data are;
Bakery A
<em> </em>= 1,880 cal
s₁ = 148 cal
n₁ = 10
Bakery B
<em> </em>= 1,711 cal
s₂ = 192 cal
n₂ = 10
df = n₁ + n₂ - 2
∴ df = 10 + 18 - 2 = 26
From the t-table, we have, for two tails, = 1.706
≈ 178
Therefore, we get;
Which gives;
Therefore, by rounding to the nearest integer, we have;
The 90% C.I. ≈ 49 < μ₁ - μ₂ < 289
Answer:
The answer is $79.45
Step-by-step explanation:
If the given 4.5 percent interest rate is a yearly rate then according to the information in the question, we can calculate Bonnie's money at the end of the three year period as:
The initial amount x interest rate x time = 70 x 0.045 x 3 = $9.45
So the amount of money after the three year period comes up to $79.45 for Bonnie.
I hope this answer helps.
Answer: 4
Step-by-step explanation: 3 + 4 = 7 and 4 x 7 is 28. If you're 16 and 12 you also get 28
There are no options, but I would assume that these sequences would be geometric: 16, -8, 4, -2, 1 -15, -18, -21.6, -25.92, -31.104, 625, 125, 25, 5, 1 can possibly be the correct ones.
