The answer is 1.0359 x 10^1 because it has to be between 10 and 1.
Answer:
H0 : μd = 0
H1 : μd ≠ 0
Test statistic = 0.6687 ;
Pvalue = 0.7482 ;
Fail to reject H0.
Step-by-step explanation:
H0 : μd = 0
H1 : μd ≠ 0
Given the data:
Before: 15 26 66 115 62 64
After: 16 24 42 80 78 73
Difference = -1 2 24 35 -18 -9
Mean difference, d ; Σd / n
d = Σx / n = ((-1) + 2 + 24 + 35 + (-18) + (-9))
d = Σx / n = 33 / 6 = 5.5
Test statistic = (d / std / sqrt(n))
std = sample standard deviation = 20.146
Test statistic = 5.5 ÷ (20.146/sqrt(6))
Test statistic = 0.6687
The Pvalue :
P(Z < 0.6687) = 0.7482
At α = 0.05
Pvalue > α ; Hence we fail to reject H0
The data does not suggest a significant mean difference in the average number of accidents after information was added to road signs.
Answer: each of two complex numbers having their real parts identical and their imaginary parts of equal magnitude but opposite sign.

Answer:
1 piece will cost 2 cents
Step-by-step explanation:
If you divide 7.91 by 0.17, you will get 0.021492, and if you round that up you will get 0.02 which is 2 cents. Now if you want to find the price of more pieces, you can just multiply 2 by however the person needs to buy, and write that as money :)))
