Question
Chapter 10, Problem 1CQQ
To determine
To conclude: About the linear correlationbetween the numbers of enrolled students and numbers of burglaries.
Expert Solution & Answer
Answer to Problem 1CQQ
There is no sufficient evidence to support the claim that there is a
Explanation of Solution
Given info:
The data shows that the numbers of enrolled students (in thousands) and the numbers of burglaries. The
Calculation:
The hypotheses are given below:
Null hypothesis:
That is, there is no linear correlation betweenthe numbers of enrolled students and the numbers of burglaries.
Alternative hypothesis:
That is, there is a linear correlation between the numbers of enrolled students and the numbers of burglaries.
Conclusion:
The P-value is 0.393 and the level of significance is 0.05.
Here, the P-value is greater than the level of significance.
Hence, the null hypothesis isnot rejected. That is, there is no linear correlation betweenthe numbers of enrolled students and the numbers of burglaries.
The critical value is ±0.878.
Here, the correlation value is 0.499 which lies between the critical values.
Hence, the null hypothesis isnot rejected.
Thus, there is nosufficient evidence to support the claim that there is a linear correlation betweenthe numbers of enrolled students and the numbers of burglaries.

3. Explain why the following statements are not correct.
a. "With my methodological approach, I can reduce the
Type I error with the given sample information without
changing the Type II error."
b. "I have already decided how much of the Type I error I
am going to allow. A bigger sample will not change either
the Type I or Type II error."
C.
"I can reduce the Type II error by making it difficult to
reject the null hypothesis."
d. "By making it easy to reject the null hypothesis, I am
reducing the Type I error."

Inflation is hitting everything else, so why not the humble nugget too, right? But your sibling thinks you’re just being dramatic—maybe you’re just extra hungry today. Determined to prove them wrong, you take matters (and nuggets) into your own hands. You march into McDonald’s, get two 20-piece boxes, and head home like a scientist on a mission. Now, before you start weighing each nugget like they’re precious gold nuggets, let’s talk hypotheses. The average weight of nuggets as mentioned on the box is 16 g each. Develop your null and alternative hypotheses separately. Next, you weigh each nugget with the precision of a jeweler and find they average out to 15.5 grams. You also conduct a statistical analysis, and the p-value turns out to be 0.01. Based on this information, answer the following questions. (Remember,…arrow_forwardBusiness Discussarrow_forward
