Answer:
Step-by-step explanation:
The z scores corresponding to the mean weight of a rotten apple relative to the apples from either orchard are, respectively,
![\dfrac{142-156}9\approx-1.56](https://tex.z-dn.net/?f=%5Cdfrac%7B142-156%7D9%5Capprox-1.56)
![\dfrac{165-156}{13}\approx0.69](https://tex.z-dn.net/?f=%5Cdfrac%7B165-156%7D%7B13%7D%5Capprox0.69)
The mean for the standard normal distribution is 0, which means that z scores closer to 0 represent data points that are more likely to occur. Therefore it's reasonable to believe that rotten apples occur more often in shipments from Zippy's.
First sequence is Arithmetic because the common difference is 4.
Second sequence is Geometric because it is multiplied by -2 each time.
Hope this helps :)
