Answer:
The 95% confidence interval for the mean change in blood pressure, 
, is 1.744 < < 2.816
Step-by-step explanation:
The parameters given are;
The number of people in the sample, n = 9
The average drop in blood pressure, = 2.28 points
The standard deviation, σ = 0.82
The confidence level = 95%
The formula for confidence interval with a known mean is given as follows;
Where:
= z - score at 95% confidence level = 1.96
We therefore have;
Which gives the 95% confidence interval for the mean change in pressure, , is given as follows;
1.744 < < 2.816
Answer:
C) A histogram because the class organizes the data into different ranges or intervals.
Step-by-step explanation:
A histogram is a graphical representation of numerical data. It is an approximate approach that groups a set of data into ranges on the x axis and having their match frequencies on the y axis.
A histogram makes it possible to represent a large amount of data and frequency in just one graph because of the interval/range option.
Because Mariner Middle school has a large number of students (550) and their height organized into equal intervals, the histogram is the best option.
