Step-by-step explanation:
Given that X is N(50,3)
So whenever we want score for x, we can convert this to Z and use std normal distribution table.
The formula for conversion is
Using this we can find out the corresponding scores
a)
Z value = 1 and hence
b)
c)
d)
e) 10th percentile is
f) This is 99th percentile

Answer:
We can use inverse sin to solve this
cos=adjacent/hypotenuse while sin=opposite/hypotenuse
therefore, cos(c)=sin(a)
if cos(c)=4/5 then BC=4 and AC =5
sin(a)=4/5
using a calculator we get 53.13010235° or just 53°

Answer:
<u>There are about 2 more students in each class at Oak Middle School than at Poplar Middle School</u>
Step-by-step explanation:
The rest of the question is the attached figure.
It is required to compares the mean number of students for the data in the plots.
The mean is sum of all divided by the number of data.
The data set of Poplar Middle School:
20,20,20,21,21,21,21,21,22,22,22,22,22,22,22,23,23,23,23,24
So, The mean = 435/20 = 21.75
The data set of Oak Middle School:
20,21,21,22,22,23,23,23,23,24,24,24,25,25,26,26,27,27,28,29
So, The mean = 483/20 = 24.15
The difference in mean = 24.15 - 21.75 = 2.4
So, the statement correctly compares the mean number of students for the data in the plots is:
There are about 2 more students in each class at Oak Middle School than at Poplar Middle School
