Answer:
5
Step-by-step explanation:
this is what I do, I see how many times 20 can go into 100, that is 5 times. and sense the mystery numbers 20% is 1, you can just leave it at 5. To double check your answer, count 1 5 times. 1 goes into 5 5 times, and 20 goes into 100 5 times.
4 thousands = 4000
7 hundreds = 700
16 tens = 160
9 ones = 9
Then you add them all together:
4000 + 700 + 160 + 9
Your answer is 4869.

Answer:
C. We have made a correct decision
Step-by-step explanation:
Hypotheses are:
: mu is less than or equal to 47
: mu is greater than 47
Type I error happens when we reject the null hypothesis but the null hypothesis was true
Type II error happens when we fail to reject the null hypothesis but the null hypothesis was wrong.
In this example we concluded that <em>mu is greater than 47,</em> thus we reject the null hypothesis. Since true mean is 52, this conclusion is true. We have made a correct decision
