I need help finding the answers for the empty blanks in the picture. Please explain the formula or how you got the answers. **Title:** Hypothesis Testing and Confidence Interval for Mean Age of Smoking Initiation**Content:**From generation to generation, the mean age when smokers first start to smoke varies. However, the standard deviation of that age remains constant at around 2.1 years. A survey of 42 smokers of this generation was conducted to determine if the mean starting age is at least 19. The sample mean was 18.2 with a sample standard deviation of 1.3. Do the data support the claim at the 5% significance level?**Notes:**- If using a Student's t-distribution for the problem, assume the underlying population is normally distributed (proof of this assumption may be required).**Parts (a) to (i):** These parts will typically guide the student through the hypothesis testing process (null and alternative hypotheses, test statistics, critical values, decision rule, etc.).**Graphical Explanation:****95% Confidence Interval Illustration:**- The graph displays a normal distribution curve.- The shaded region in the center indicates the 95% confidence interval (C.I.).- The horizontal line beneath the curve represents the range of possible sample means.- Two vertical bars mark the lower and upper bounds of the confidence interval.- A box in the middle represents the point estimate (the sample mean). **Instructions:**- Construct a 95% confidence interval for the true mean.- Sketch the graph of the situation.- Label the point estimate and the lower and upper bounds of the confidence interval.- Round your calculated bounds to two decimal places.**Additional Materials:**- eBook (linked resource for further reading)Use these instructions and provided data to complete the hypothesis test and confidence interval calculations, verifying if the mean starting age is significantly different from 19 years at the 5% level.
