Answer:
21.6 hours
Step-by-step explanation:
Hypothesis testing allows to identify a event test. The correct order of the steps of a hypothesis test is given following
1. Determine the null and alternative hypothesis.
2. Select a sample and compute the z - score for the sample mean.
3. Determine the probability at which you will conclude that the sample outcome is very unlikely.
4. Make a decision about the unknown population.
These steps are performed in the given sequence to test a hypothesis.
The principal tests the hypothesis with a mean of 21.6 hours for the determination of average amount of time spent watching television.
Length is 120 and the width is 60, because 60×2= 120 and when you add 120+60=180
Step-by-step explanation:
20% of the coins are dimes, and 10 coins are selected, so the expected number of dimes is 0.20 * 10 = 2.
So the number generator is fair. It shows that 20% of the coins selected are dimes most of the time.
It is in the tenths place, 7/10
