Mrs. Miller claims that 10% of the marbles in the jar are purple. Do the students have statistically significant evidence that the true proportion of purple marbles in the jar is greater than 10%? Use the sampling distribution to help answer the question.

If they nenenenenenene

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
