The students in a class collected data on the number of minutes per day some kids spend
brushing their teeth. Their data is shown in the dot plot below.

Which statement correctly describes these data?
A
The median is 0.5 and the mean is less than the median
B
The median is 0.5 and the mean is greater than the median
The median is 1.5 and the mean is less than the median
D
The median is 1.5 and the mean is greater than the median

i dont know i just need points

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;

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .
