Which ratio is equivalent to the ratio 33:39? A. 26:22

B. 22 to 26

C. 22 to 13

D. 13:22

9514 1404 393

  B.  22 to 26

Step-by-step explanation:

Multiply each value in the ratio by 2/3 to see an equivalent that is among the choices.

  33 : 39 = (2/3)(33) : (2/3)(39) = 22 : 26

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;
