Solution: Note: Hello! As you have posted more than 3 sub parts, we are answering the first 3 sub-parts. In case you required unanswered sub parts also, kindly re-post those parts separately. The given data isa. From the given information, it can be observed that the largest value is 30 and the smallest value is 13. The range is Thus, the range is 17.b. Hence, verified.c. Thus, the sample variance is 41. Thus, the sample standard deviation is 6.40.

Answered: Given the sample data. x: 23, 19, 13,…
