After Halloween, your statistics instructor wanted to find out if there was a significantly different number of Smarties per box. Eight 50-gram boxes of Smarties were randomly selected and the number of Smarties that were in each box were counted. Amazon's Alexa indicates that there are a mean of 45 Smarties in a 50-gram box. The number of Smarties in the 8 boxes was 40 52 55 45 48 45 50 60. Test the hypothesis at the 5% significance level (α = 0.05) using the 5-step hypothesis testing procedure (show ALL steps). Make sure to clearly state the null and alternative hypotheses in formal notation. Round all values to 2 decimal places.
