Which of the following describes a situation in which the total distance a tennis player travels is 0 meter from his starting point? a the player runs 9 meters forward and then runs 0 meters in the opposite direction. b the player runs 5 meters forward and then runs 6 meters in the opposite direction. c the player runs 7 meters forward and then runs 7 meters in the opposite direction. d the player runs 6 meters forward and then runs 5 meters in the opposite direction.

The answer is C The player runs 7 meters forward and then runs 7 meters in the opposite direction.

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;
