Malin and George kept track of their running times for the 100-yard dash. The dot plots below show their results.

Based on the data represented in the graphs, which statement appears to be true?

A The median running time for both sets of data is 13.

B The distribution for both sets of data is approximately symmetrical.

C The range of the running times for George is greater than the range of
the running times for Malin.

D The mode for both sets of data is equal.

step-by-step explanation:

mean or average is 40.6

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;

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.
