"According to Dietary Goals for the US (1977), high sodium intake may be related to ulcers, stomach cancer, and migraneheadaches. The human requirement for salt is less than 220 milligrams per day, which is surpassed in most single servings of ready-to-eat noodles. If a random sample of 22 similar servings of noodles has a mean sodium content of 210 milligrams and a standarddeviation of 5.23 does this suggest at the 0.01 level of significance that the average sodium content for a single servings of noodlesis less than 220 milligrams?What are the given information?population mean:Blank 1sample mean:Blank 2sample standard deviation:Blank 3sample size:Blank 4level of significance:Blank 5degrees of freedom:Blank 6What is the critical value?t:Blank 7What is the calculated t?t:Blank 8"
