Answer:
Range
Step-by-step explanation:
110-76=34
C.) R because the third letter in the angle PQRS is "R"
Answer:
a. n= 47
b. n= 128
Step-by-step explanation:
Hello!
The objective of this experiment is to test if the new catalyst, XA-100, increases the mean hourly yield of a chemical process, that is known to be μ=750 (pounds per hour) with the current process.
You need to calculate the sample size to estimate the population with determined error margins.
To do so, since you have no population information, only that it is approximately normal distributed, you'll use the Student t statistic to get the sample size.
The formula of the margin of error (d) is:
d=
* (
)
I've cleared the sample size of the formula

You need a sample size for the t-Student value and a standard deviation, that's why the information of a pilot study with n=5 and S= 19.62 is given.
a)
95% CI
d= 8 pounds


n= 46.35 ≅ 47
b)
99% CI
d= 5 pounds


n= 127.49 ≅ 128
I hope it helps!
The cheaper price among this set of orange sales is the one done by trader B, who sells <u>8 for N120</u>.
<h3>How is the cheaper price determined?</h3>
The cheaper price can be computed by finding out the price per unit.
<h3>Data and Calculations:</h3>
Price of Set Unit Price
Sale of 6 oranges N100 N16.67 (N100/6)
Sale of 8 oranges N120 N15.00 (N120/8)
Thus, selling 8 oranges for N120 is cheaper than selling 6 oranges for N100, and <u>N1.67</u>.
