Please help with b and c as quickly! Thank you Exercise 4ALimit your attention to the most “recent” temperature data, (which we define as years 1990-2013), for New York City. Answer the following questions:a) For how many years during the recent period, did the annual temperature rise above thehistorical mean calculated for the entire period? Does this represent a reasonable, relativelylarge or relatively small percentage of the recent years?b) Of the 25 warmest years in recorded history, what percentage occurs during the recentperiod? Do you think the recent period has more or less than its fair share of warmer years?(Hint: It may help to re-sort the data according to temperature).c) Is the mean temperature for the recent period higher or lower than that of the entire period?Calculate the z-score for the recent mean based on the mean and standard deviation for theentire period. What does the value of the z-score tell you about the difference between thetwo means?d) Draw a Box Plot…
