Which statement is true? Select all that apply. Graph of a diagonal line on a coordinate plane going up and to the right with Time (sec) on x-axis and Height above Sea Level (ft) on y-axis. When sec is 0, ft is 0. When sec is 4, ft is -12
A.

The relationship is proportional.
B.

The slope is –6.
C.

The slope is negative.
D.

The y-intercept is –3.
E.

The equation of the line is y = –3x.

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;
