Arandom sample of 85 adults found that average calorie consumption was 2,100 per day. previous research has found a standard deviation of 450 calories, and you assume this value for . a researcher has been given $10,000 to conduct a similar survey, which costs $50.00 per person surveyed. she must compute a 95% confidence interval. given her budget restriction, what would the minimum margin of error be for the confidence interval for the population mean?

Average consumption, p = 2,100
Standard deviation assumed from previous studies, sd = 450
Z (at 95% confidence interval) = 1.96
Amount of funds available = $10,000
Cost per person supplied = $50.00

Therefore,
Sample size, n = 10000/50 = 200

Minimum margin of error will be achieved when the sample size is bigger than 85 adults.

Margin error = Z*sd/Sqrt (n) = 1.96*450/Sqrt (200) = +/- 62.37

Additionally,
Lowest range = 2100-62.37 = 2,037.63
Highest range = 2100+62.37 = 2,162.37

The purpose of any leavener is to produce the gas that makes bread rise. Yeast does this by feeding on the sugars in flour, and expelling carbon dioxide in the process.

While there are about 160 known species of yeast, Saccharomyces cerevisiae, commonly known as baker's yeast, is the one most often used in the kitchen. Yeast is tiny: Just one gram holds about 25 billion cells. That amount of fungi can churn out a significant amount of carbon dioxide, provided it has the simple sugars it uses as food. Fortunately, yeast can use its own enzymes to break down more complex sugars—like the granulated sugar in the activity below—into a form that it can consume.
