<h3>
Answer: 8.323 (approximate)</h3>
====================================================
Explanation:
s = 32 = sample standard deviation
n = 40 = sample size
Despite not knowing the population standard deviation (sigma), we can still use the Z distribution because n > 30. When n is this large, the student T distribution is approximately the same (more or less) compared to the standard Z distribution. The Z distribution is nicer to work with.
At 90% confidence, the z critical value is roughly z = 1.645. This can be found using either a Z table or a calculator.
------------------
We have these values:
- z = 1.645 (approximate)
- s = 32
- n = 40
Plug these values into the margin of error formula.
The margin of error is roughly 8.323
I rounded to 3 decimal places because z = 1.645 is rounded to 3 decimal places. If your teacher wants some other level of precision, then be sure to follow those instructions.
Answer:
Maylin should purchase one unit of each socks & jogging shorts.
Step-by-step explanation:
In case of two goods, consumer is at equilibrium when marginal utility per dollar spent on last unit of the goods are equal, ie MU 1 / P1 = MU 2 / P2 (MU are the marginal utilities / marginal benefit of two goods, P are the price of two goods)
Given : MU1 (So) = 20, MU2 (JSh) = 30, P1 (So) = 10, P2 (JSh) = 15
So, equilibrium is at where MU1 (So) / P1 (So) = MU2 (JSh) / P2 (Jsh)
20/10 = 2, & 30/15 = 2. MU's per dollar are equal for both.
So Maylin is in equilibrium, she should purchase one unit of each socks & jogging shorts.

Answer:
Solution: 106% off 795 is equal to (106 x 106) / 100 = 842.7. So if you buy an item at $795 with 106% discounts, you will pay $-47.7 and get 842.7 cashback rewards
