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
Answer:
-5/3 is less than (<) square root of 3
Step-by-step explanation:
-5/3 = -1.66666...
square root of 3=1.73205080...
either way the square root would be greater because the answer cant be negative. And negative is always less then a positive.
Hope this helps!
12. Since there is no table given I will assume that what you want me to do is to show that Unit rate of Brandon’s biking.
SO here are the data that we need:
=> 8 and ½ miles = 8.5 miles
=> ½ hour = .5 hours or 30 minutes
Now, let’s solve for the unit rate
=> SO in every 30 minutes he bikes around 8.5 miles
=> Since 1 hour is equals to 30 minutes, simply multiply 8.5 by 2
=> 8.5 * 2 = 17miles
=> 17 miles / hour
Can you please put this question in english
