Running head: STATISTICS 1 Statistics Name of Student Name of Professor Course Title Date STATISTICS 2 Solution Minimum point =72 Maximum point =107 Temperature Frequency Cumulative frequency 75-75 3 3 75-80 6 9 80-85 8 17 85-90 5 22 90-95 7 29 95-100 3 32 100-105 0 32 105-110 3 35 STATISTICS 3 Range =35 N/2=35/2=17.5 Median =1+([N/2-m]/2) *C=85+([17.5-17]/5) *5 Therefore; Median =85.5 False: Explanation: This is based on the fact that; extreme values do not have any impact on the median. Extreme values affect the mean only but doesn’t affect median. Hence the given statement is false. STATISTICS 4 False, Explanation: If the variance of the given data set is zero, then all observations should or must be same. Hence the above statement is zero. True: This is based on the fact that; standard deviation is obtained through getting a square root of its variance. Hence, we don not have a square root of a negative number meaning that all square root values are and must be positive. Alternatively, standard deviation cannot be negative since squaring all deviations generates a list of all positive numbers. False: Explanation: in some cases, variance may be zero. Zero is neither a positive nor a negative value. In such a case, we can conclude that variance of data is not always positive or negative value. Explanation: based on the data given in the graph, the trend of data can be said to be reverse resulting to a negative correlation. There ...
