The Shapiro-Wilk test is specifically designed to test the hypothesis. H0: Y has a normal distribution versus H1: Y does not have a normal distribution. Jessie obtains a normal sample of size n = 400 for Y = smoothness of a 3-D printed surface. Her choice for alpha is 0.025 and the Shapiro-Wilk test gives her p-value = 0.023. Which (one) of the following should she do? 1. Reject the alternative hypothesis because it has only a 2.3% chance of...

Use the Empirical rule to determine the following areas as the probabilities 21 How big is the area (probability) of zone "B"7 22. How big is the area (probability) of zone "D"? The mean height of males 20 years or older is 68 inches with a standard deviation of 3.53 inches. The mean height of females 20 years or older is 62 inches with a standard deviation of 2.53 inches. While a male is 75 inches tall, a female is...
I am running a shapiro test in rstudio and the answer that it is returning doesn't make any sense. What am I doing wrong? >shapiro.test(data1$maxfwt) W= 0.88286, p-value= 1.911e-08 There are about 100 values in the dataset and some of them are the same. If I run any of the columns in the dataset I get a similar result with an e- in the p-value.

The FloridaLakes dataset describes characteristic of water samples taken at random Florida lakes. Acidity (pH) is given for each lake. Pure water has a pH of 7, which is neutral. Solutions with a pH less than 7 are acidic while solutions with a pH greater than 7 are basic or alkaline. The researchers would like to know whether on average the solutions in Florida lakes are acidic. The following two problems are based on this dataset. Problem 1 This problem...
