Answer:
We conclude that the calibration point is set too high.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 1000 grams
Sample mean, = 1001.1 grams
Sample size, n = 50
Alpha, α = 0.05
Population standard deviation, σ = 2.8 grams
First, we design the null and the alternate hypothesis
We use One-tailed(right) z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We reject the null hypothesis and accept the alternate hypothesis. We accept the alternate hypothesis. We conclude that the calibration point is set too high.
Answer:
10. ○
9. ○680%
8. ○40%
7. ○
6. ○0,4, 40,5%, 11⁄25, 4⁄9
5. ○
4. ○1%
3. ○76%
2.
1.
Step-by-step explanation:
10. To convert from a percentage to a decimal, move the decimal mark twice to the left; each 20 is worth 5, and since 5 by 17 is 85, you have your fractional part of 17⁄20, then attach the whole number of 4.
9. To convert from a mixed number\improper fraction to a percentage, first evaluate the fractional part for a decimal answer, then move the decimal mark twice to the <em>right</em>.
8. To convert from a fraction to a percentage, evaluate the fraction for a decimal answer, then move the decimal mark twice to the right.
7. 60%
Greatest Common Divisor [GCD]: 44
6. 44%
_
44,4%
40%
Now that these are all percentages, it is alot easier to order them from least to greatest.
5. To convert from a percentage to a decimal, move the decimal mark twice to the <em>left</em>.
4. To convert from a decimal to a percentage, move the decimal mark twice to the <em>right</em>.
3. Each 25 is worth 4, and since 4 by 19 is 76, you get 76%.
2. Each 25 is worth 4, and since 4 by 6 is 24, you get 24%, and this graph.
1. Each 36 is worth 2 7⁄9, and since 12 by 2 7⁄9 is 33⅓, you get 33⅓%, so you would choose this answer.
