Answer:
A. Fail to reject the claim that the average math SAT score is 498 when in fact it is not 498.
Step-by-step explanation:
Type II Error:
A type II error happens when there is a non-rejection of a false null hypothesis.
In this question:
The null hypothesis is H0:μ=498.
Since there is a type II error, there was a failure to reject the claim that the average math SAT score is 498 when in fact it is not 498, and thus, the correct answer is given by option A.
12 groups in a 1:1 ratio of boys:girls. there are only 12 girls so one in each group + 1 boy per group gives you 12 groups. with a remainder of 6 boys
Answer: There are approximately 853827 new cases in 6 years.
Step-by-step explanation:
Since we have given that
Initial population = 570000
Rate at which population decreases is given by
Now,
First year =570000
Second year is given by
Third year is given by
so, there is common ratio ,
it becomes geometric progression, as there is exponential decline.
so,
a=570000
common ratio is given by
number of terms = 6
Sum of terms will be given by
We'll put this value in this formula,
So, there are approximately 853827 new cases in 6 years.
