Answer:
Step-by-step explanation:
From the information given:
The type 1 error is rejecting when
The meaning of Type 1 error is rejecting the claim that the mean running time is 9.7 hours when actually the mean running time is greater than 9. 7 hour.
The mean is 0.0118 approximately. So option C is correct
<h3><u>Solution:</u></h3>Given that , The probability of winning a certain lottery is for people who play 908 times
We have to find the mean number of wins
Assume that a procedure yields a binomial distribution with a trial repeated n times.
Use the binomial probability formula to find the probability of x successes given the probability p of success on a single trial.
Hence, the mean is 0.0118 approximately. So option C is correct.
