Kindly Keep Explanations Brief

1 . 2 . Quality Control [QC] Experiment The heights of Ferry Morse zinnias are known to be normally distributed. You work in qualityr control {QC} for Ferry Morse. Periodically, you plant all of the 15 seeds in a packet and record the final height of each plant (in inches}. This time you get these results: 21.5 24.3 21.6 23.5 24.3 24.1 27.2 25.3 20.1 19.5 22.1 22.1 23.1 22.7 26.9 Form a 95% confidence interval for the proportion of Ferry Morse zinnias that grow to over 24 inches. a. Complete the statement: \"I'm % condent that the proportion of Ferry Morse zinnias that grow to over 24 inches is between and inches\". b. If you want to be more confident, say 99%, would the resultant confidence interval be wider or narrower? Explain. Form a 95% confidence interval for the mean height of Ferry Morse zinnias. a. Complete the statement: "I'm % confident that the mean height of Ferry Morse zinnias is between and inches"b. How many zinnia heights would you need for a 99% confidence interval with the same margin of error? c. If 100 trials of the QC experiment are performed, each with its own packet of seeds, how many of the resulting 99% confidence intervals would you expect to contain the true mean height of Ferry Morse zinnias
