3. Find the lower-limit and upper-limit of an interval such that we have a confidence level of 95% that the population mean is in this interval. Use "print" or "cat" function to present these limit values. (Use z-distribution and not t-distribution. Find za by coding not by using a table) (6 points) 1 consumption 2 25.93 3 29.31 4 31.41 сл 5 39.33 6 74.55 7 69.74 8 86.95 9 50.88 10 42.82 11 55.08 12 35.68 13 8.52 14 15.94 15 11.29 16 25.89 17 36.08 18 69.37 19 65.48 20 80.04 21 72.46 22 56.12 23 42.84 24 39.1 25 8.28 26 6.8 27 35.42 28 25.94 29 40.57 30 48.06 31 60.88 32 106.09 33 68.26 34 64.68 35 42.28 36 30.14 37 19.67 38 10.22 39 25.05 40 13.27 41 15.54 42 57.32 43 60.46 44 72.9 45 84.5 46 60 47 43.64 48 14.69 49 10.18 50 5.6 51 22.27 52 16.05 53 24.79 54 30.36 55 71.91 56 55.94 57 71.72 58 58.54 59 59.19 60 30.22 61 4.4 62 3.27 63 25.8 D 21 64 25.31 65 41.6 66 43.27 67 75.99 68 78.99 69 92.77 70 63.61 71 48.39 72 35.3 73 7.29 74
