The Baltimore Zoo feeds their elephants a combination of fruit and grass. The zookeeper would like to create a model to represent how much food the elephants eat. Each morning, the zookeeper puts out 22 pounds of fruit and an additional 30 pounds of grass per elephant. Which of the following models the linear relationship between the total weight of elephant food, f(x), based on the number of elephants, x? Select all that apply.

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
