I just need part b. I need the p-value for part b, please.

**Exercise on Correlation and Linear Regression**

**Overview:**

This exercise explores the relationship between daily temperatures and the number of patients admitted for winter illnesses in a small clinic. A joint sample of ten data points (X, Y) is provided:

- Data Points: (70,3), (77,1), (68,7), (67,7), (61,13), (83,0), (73,2), (66,8), (81,1), (90,0)

Where:
- X represents the average temperature of the day.
- Y signifies the number of patients admitted with winter illnesses.

**Tasks:**

A. **Compute the Linear Correlation Coefficient (r):**
   - Find the correlation coefficient and explain its meaning in the context of the data.

B. **Hypothesis Test for Slope (Significance Level 0.01):**
   - Test if the true slope of the regression line is negative at a 0.01 level of significance.

C. **Prediction for Temperature 82:**
   - Estimate the average number of patients with winter illnesses if the temperature is 82.

D. **Prediction for Temperature 60:**
   - Estimate the average number of patients with winter illnesses if the temperature is 60.

E. **95% Confidence Interval for True Slope:**
   - Construct and interpret a 95% confidence interval for the true slope of the linear relationship.

F. **Test the Predictive Power of Temperature:**
   - At 0.01 significance, determine if temperature is a good predictor for the average number of winter illness patients.

G. **Report the Sum of Squared Residuals (SSE):**
   - Calculate the sum of squared residuals to assess the variation of data points around the fitted regression line.

H. **Conclusion on Temperature and Illness Correlation:**
   - Based on items A-G, discuss if a lower temperature correlates with a higher number of winter illness patients.

**Note:** This exercise utilizes linear regression analysis to understand and predict trends in healthcare data.
