If x is number of ‘ones’ then assuming binomial x ~ b(40, 0⋅25) and using the cumulative binomial tables the test statistic (observed value) is x = 6 p(x ≤ 6 ‘ones’ in 40 rolls) = 0⋅0962 = 9⋅62% since 9⋅62% < 10% the test statistic (observed result) lies in the critical region. we reject h0 and conclude that.

Skill 2: systematic sampling. a systematic sample selects every nth member of a population. to create a systematic sample, give every member of the population unique, sequential numbers, then select a start number a, then a n, then a 2n, etc. choose a randomly but less than n and choose n such that you get the sample size you desire.
