The parameter of interest is the population mean difference in weight , where the difference is defined by actual weight - ideal weight. (0.6 pt) What is the null hypothesis for this test? Null hypothesis is there is not a mean difference in actual weights vs ideal weights. What is the alternative hypothesis for this test? Alternative hypothesis is there is a mean difference between the weights. Is this a one-sided test or a two-sided test? Two-sided test- we want to know what the difference is regardless of direction. 5. One assumption for this test is that the population of differences has a normal distribution. Create the appropriate plot to check this assumption and paste it into your solutions document
