Please answer question 9.16 half of the question is in one photo and half is in another. Please provide t critical value, t calculated value, and if you rejected or accepted the null hypothesis that ponds have lower hardness

The image contains text from a page discussing statistical values and concepts relating to water hardness in Kansas. Here's the transcription of the visible portion:

"9.16 Suppose that the mean water hardness of lakes in Kansas is 425 mg/L, and these values tend to follow a normal distribution."

**The Paired t-Test**

The following data are for pre-exercise and post-exercise body temperature measurements for eight young adults. Is there a difference in mean body temperature following exercise?

- **Individual Number**: 1, 2, 3, 4, 5, 6, 7, 8
- **Resting**: 994, 291, 360, 385, 500, 558
- **Post-exercise**: 381, 398, 434, 562, 496, 485, 446, 479, 422

**Example Exercise:**

An investigation is conducted to determine whether there is a significant change in body temperature due to exercise. The pre-exercise and post-exercise body temperatures are gathered for eight individuals to perform a paired t-test analysis.

**Instructions:**

1. Calculate the difference in temperatures for each individual before and after exercise.
2. Use the differences to find the mean and standard deviation.
3. Formulate the null and alternative hypotheses.
- Null hypothesis (H0): There is no difference in mean body temperature before and after exercise.
- Alternative hypothesis (H1): There is a difference in mean body temperature before and after exercise.
4. Compute the test statistic and compare it with the critical value to determine if the null hypothesis can be rejected.

Given the “data” determined by y = x^3 + (x-1)^2 with x = 0.1, 1.2, 2.3, and 2.9, calculate SSTO, SSR, and R^2. Then recalculate these using x = 0.3, 1, 2.45, and 2.8. Does where you collect your data (i.e., which values of x) appear to impact your interpretation of how good the linear model fits?.
Consider the following variables: Y=daily productivity score (measured in points) X1=0 if undergraduate student,1 if graduate student X2=hours of sleep per night 1. The plot shown below could possibly be the graph of which model? 2. If you want to test whether type of student modifies the association between hours of sleep per night and daily productivity score, which model should you consider and what is the null hypothesis for this test? 3. Suppose you use Model 5 to describe the relationship between type of student, hours of sleep per night, and daily productivity score. You use the method of least squares to obtain: Y = -0.5 + 3 (X1) + 1.5 (X2) + 2.5 (X1)(X2).
