Arandom sample of 85 adults found that the average calorie consumption was 2100 per day. previous research has found a standard deviation of 450 calories, and you use this value for \sigma σ. a researcher wants to estimate a 95% confidence interval and is willing to accept a margin of error of \pm 50 ± 50 calories. she knows it will cost $50 to survey each member of the sample. given this information, how much will it cost to survey the minimum number of people?

$15600

Step-by-step explanation:

Minimum number of samples can be calculated using the formula:

N≥ where

N≥ =311.2

Therefore, minimum required sample size for 50 cal standard error in 95% confidence is 312

Since the survey costs $50 for each person then the survey costs minimum

50*312=$15600

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
