The line of best fit for a scatter plot is shown: A scatter plot is shown. Data points are located at 0 and 8, 2 and 8, 4 and 5, 6 and 3, 6 and 5, 6 and 7, 9 and 4, 10 and 2. A line of best fit passes through the y-axis at 8 and continues downward passing through the point 6 and 5.
What is the equation of this line of best fit in slope-intercept form? (4 points)

a
y = negative one half x + 8

b
y = −2x + 8

c
y = −8x + one half

d
y = −8x + 2

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;

multiple all that
