(a) Determine the 30th percentile for the number of chocolate chips in a bag. (b) Determine the number of chocolate chips in a bag that make up the middle 98% of bags (c) What is the interquartile range of the number of chocolate chips in a bag of chocolate chip cookies? (a) The 30th percentile for the number of chocolate chips in a bag of chocolate chip cookies is chocolate chips Round to the nearest whole number as needed.)Explanation / Answer
a) 30th Percentile = -0.5244*118+1261 = 1199
b) Middle 98% Lower value = -2.326*118+1261 = 986
Middle 98% Lower value = 2.326*118+1261 = 1536
c) IQR = 0.67*118+1261-(-0.67*118+1261) = 159
