"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 27 similar servings of noodles has a mean sodium content of 240 milligrams and a standarddeviation of 6.64 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"

For a normally distributed population with a mean of 35 and a standard deviation of 7.5, what value of X would be exceeded only 10% of the time?
According to the Center for Disease Control and Prevention (CDC), the mean life expectancy in 2015 for non‑Hispanic black females was 78.1 years. Assume that the standard deviation was 15 years, as suggested by the Bureau of Economic Research. The distribution of age at death, ?, is not normal because it is skewed to the left. Nevertheless, the distribution of the mean, x¯, in all possible samples of size ?n is approximately normal if ? is large enough, by the central limit theorem. Let x¯ be the mean life expectancy in a sample of 100 non‑Hispanic black females. Determine the interval centered at the population mean ? such that 95% of sample means x¯ will fall in the interval.

1. The quality of the drinking water must be monitored as often as possible. One variable of concern is the pH level, which measures the alkalinity or acidity of the water. A pH below 7.0 is acidic while a pH above 7.0 is alkaline. A pH of 7.0 is neutral. A water-treatment plant is targeting higher than 8.0 pH. Based on 16 random water samples, the mean and standard deviation were found to be: Xbar=7.6 and s = 0.4. Test the claim using 5% level of significance.a.
