so i need this for a math problem on my math subject but i forgot how to do this can you guys help me please its due soon :)

(5,-3)

Step-by-step explanation:

You just find the middle #

(3,-1)  and   (7,-5)

the middle point of 3 and 7 is 5

the middle point of -1 and -5 is -3

so (5,-3)

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

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;
