Answer:
The right answer is:
a.H0: μd = 0; H1: μd > 0
Step-by-step explanation:
The claim that want to be tested is that the sales were significantly increased after the commercial, indicanting that the advertisement campaign was effective.
This claim is usually expressed in the alternative hypothesis as it has to have enough evidence to prove that it is true.
Then, the alternative hypothesis H1 should state that the difference (sales after - sales before) is higher than 0.
The null hypothesis would state that the difference is not significantly different from 0, or, in other words, that the sales are the same before and after and that the variation is due to pure chance.
Then, the null hypothesis H0 would state that the difference is equal to 0.
The right answer is:
a.H0: μd = 0; H1: μd > 0
Two angles that added together equal 90 degrees
Answer:
i
Step-by-step explanation:
i^ even power
i^2 = i*i = -1
i^4 = =1
So raised to an even power, it will be either 1 or negative 1
raised to an odd power it will be either i or -i
The Answer
LCD = 12
Equivalent Fractions with the LCD
2/3 = 8/12
3/4 = 9/12
1/2 = 6/12
Solution:
Rewriting input as fractions if necessary:
2/3, 3/4, 1/2
For the denominators (3, 4, 2) the least common multiple (LCM) is 12.
LCM(3, 4, 2)
Therefore, the least common denominator (LCD) is 12.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
2/3 = 2/3 × 4/4 = 8/12
3/4 = 3/4 × 3/3 = 9/12
1/2 = 1/2 × 6/6 = 6/12
