The graph above is what we call a quantitative dot plot. Each dot represents a specific number of
observations from a set of data. (Unless otherwise indicated, assume that each dot represents one
observation. If a dot represents more than one observation, that should be explicitly noted on the plot.)
The dots are stacked in a column over a category or variable, so that the height of the column
represents the relative or absolute frequency of observations in the category,
Using the dot plot above, answer or complete the following questions and tasks.
What is the quantitative variable being measured?

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;
