Answer:
60 students
Step-by-step explanation:
The confidence interval of a proportion is given by:
Where 'p' is the proportion of students who responded 'yes', 'z' is the z-score for a 95% confidence interval (which is known to be 1.960), and 'n' is the number of students in the sample.
If the confidence interval is from 0.584 to 0.816, then:
60 students were in the sample.

The appropriate measure of central tendency is one that shows
difference and is suitable for a scale that is nominal.
Response:
- The measure of central tendency to use is the <u>mode</u>.
<h3>How can the appropriate measure of central tendency be selected?</h3>
The mean is the sum of the measurements divided by the number count
of the plants.
The mode is the measurement that has the highest frequency.
The median is the measurement of the middle plant when arranged in a
given order according to size.
To argue that there is a difference between the plants, the measure of
central tendency to use is the mode, given that the data involves
measurements which can be expressed in a nominal scale.
Therefore;
- The measure of central tendency that will be best for Mrs. Hull to use is the<u> mode</u>

Willow = 63in
Jayder = 6ft 5in
1 foot equals 12 inches
6x12=72
So 72 inches plus 5 inches equals 77
So now you subtract Willows height from Jaydens height
77 - 63 = 14
Jayden is 14 inches taller
Answer:
y = 40 x = 80
Step-by-step explanation:
520 = 3.25x + 6.5y x+y=120
x+y=120
x = 120-y
520 = 3.25(120-y)+6.5y
520 = 390-3.25y+6.5y
520 = 390+3.25y
130=3.25y
Divide each side by 3.25
40 = y
x = 120-y
x = 120-(40)
x = 80
