Answer:
1. χ² = 18.548
2. χ² = 23.685
Step-by-step explanation:
1. Confidence level is 99% (α = 0.01), but we're only interested in the left half, so α/2 = 0.005. Degrees of freedom are 7−1 = 6. Looking up in a chi square table, χ² = 18.548.
2. Confidence level is 90% (α = 0.10), but we're only interested in the right half, so α/2 = 0.05. Degrees of freedom are 15−1 = 14. Looking up in a chi square table, χ² = 23.685.
The volume of your box is 19 times 17 times 6. You will get 1938 in. cubed.
Answer: 1%
Explanation:
Add up the frequencies in the bottom row: 350+200+245+125+66+10+4 = 1000
There are 1000 families total. Of this total, 10+4 = 14 families have more than six people. I added up the frequency counts for "7 people" and "8 people" to get 14.
Divide 14 over 1000 and we get 14/1000 = 0.014 = 1.4% which rounds to 1%
Answer:
38 1/4
Step-by-step explanation:
First I convereted 8 1/2 and 4 1/2 to fractions, because it is easier for me, which gives you
8.5*4.5
Multiplying this out you get 38.25, which is equal to 38 1/4.
If you do it by fractions you convert them to inproper fractions.
8 1/2= 17/2
4 1/2= 9/2
You then multiply and get 153/4
When you divide 153 by 4 you get 38 1/4
We don’t know how many she can bake, we only know how many she can decorate. It’s a trick question. Sorry if I’m wrong. Hope this helps!
