Answer:
Null Hypothesis, :
= 0
Alternate Hypothesis, 0
Step-by-step explanation:
We are given that a local insurance agent randomly selected profiles for 10 of his clients and checked online price quotes for their policies.
Then, based on paired data on the 10 clients (the price he offered them and the corresponding online quote), he obtained t-statistic = 0.709 p-value = 0.248.
Here , we will use the concept of Paired data test statistics because the prices that the local insurance agent offered and the corresponding online quotes are from the same single data. These information has not been taken from the two independent samples.
So, <u>Null Hypothesis</u>, :
= 0
<u>Alternate Hypothesis</u>, 0
Here, null hypothesis states that there is no difference between the price he offered them and the corresponding online quote.
On the other hand, alternate hypothesis states that there is difference between the price he offered them and the corresponding online quote.
Hence, this would be the correct null and alternative hypothesis.
Answer:
Step-by-step explanation:
Notice when x increases 1, y is 4 times the previous one, so
the function is like
To determine the constant C, put any pair of (x, y)
Use x = 0, y = 0.2, so
0.2 = = C * 1 = C
then
The interval 
corresponds to the part of the distribution lying within 2 standard deviations of the mean (since 500-2*100=300 and 500+2*100=700). The empirical rule states that approximately 95% of the distribution is expected to fall in this range.
