A cereаl cоmpаny stаtes that the average weight оf cereal in their bоxes is 500 grams. The population standard deviation of the cereal weight is known to be 20 grams. A quality control engineer believes that the actual average weight may be different from 500 grams. They take a random sample of 64 boxes and find that the sample mean weight is 506.9 grams. At a significance level of α = 0 . 01 , test whether there is enough evidence to say the average weight of the cereal is different from 500 grams. There [BLANK-1] (is/is not) sufficient evidence at the [BLANK-2]% level of significance to [BLANK-3] (support/reject) the claim.
