Question

(a) 305 and 375 grams (Use ascending order.) (b) 95 % (Type an integer or a decimal.) (c) 5% (Type an integer or a decimal.) (d) 97.35 % (Type an integer or decimal rounded to two decimal places as needed.)

Answer 1

saution d. According to Empedical suletudod 684. of valuer fall - mean Isd g 95% of values fall. = mean f asd 99.14. of values fall = mean 3sd теоо ш - хор 681. of the data lies bw two standard denicitions of the mean (ur, utr) Vis flere (300-40, 300 4) = (260, 340) . 684. the grams will be blo 260 and 340 grams • 99.74. If the data lies blw three standard deviations of the mean W-3t = 300-3(40) = 180 de Mt3t = 300+3 (40) = 420 ... so the percentage of organe weight blw 180 and 420 grams = 99.7%. c) As 99.11. the data liec bw 180 and 420 so the percentage of data lying below 180 and above 420 would be 0.3% ... Hence we can say that percentage of grans weight less than 180 and or more than 420 grams = 0.3%. d) 68% of organs weight be ll-r - 300 - 40 = 260 ut = 300 + 40 = 340

- 954. f the data lies lw And as the 220 and 380 grams bell Curve is symme taric about its near so the percentage of data lying below 250 would be equal to the percentage Ⓡ data lyong abore 380 = 2.54. 1. Similarly 68y of data lies blo 160 and 340. so the percentage of data lying below 260 would be equal to percentage of date lying above 340 = 32/2 = 16%. ... The percentage of data lying blo 220 and 340 grams = (percentage of data blo 220 8.260) + (percentage of data blo 260 and 340) = 13.5% + 684. 81-5). 1 3.54 341. zw.
