The table shows how much Kim earned from 1996 to through 2004. (table year= X and annual salary=y)
Year
1996
1998
2000
2002
Annual Salary
($)
42,000
47,500
48.900
55,000
60,000
2004

What is the equation of a trend line that models an approximate relationship between time and Kim's annual salary? Let 1996 = 0.

A y = 2200x + 40000; x is the current year, y is annual salary
B. y = 1996x + 42000; x is slope, y is annual salary
C. y = 2200x + 40000; x is years since 1996;y is annual salary.
D. y = 40000x + 2500; x is years since 1996;y is annual salary.

i would pic false cause it goes down towards negative

step-by-step explanation:

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;
