90 words in 4 minutes is the same as 45 words in 2 minutes because you divide both sides by 2. 2 goes into 10, 5 times, so 45x5=225.
You can expect her to type 225 words in 10 minutes.

Step-by-step explanation:
Given from the question;
Mean=8.4 hrs=μ
Standard deviation=1.8 hrs=δ
Sample size, n=40
Let x=8.7
z=(x-μ)÷(δ÷√n)
Find z(8.7)
z=(8.7-8.4)÷(1.8÷√40)
z={0.3×√40}÷1.8=1.05409
z=1.0541
Read from the standard normal probabilities table
P(z>1.0541)
=0.1459

Step-by-step explanation:
A histogram is simply a graphical visualization of the distribution of a particular variable or data set. Besides, a histogram accurately represents the distribution of numerical data and estimates of the probability distribution of a a given continuous variable.
There exist a number of software which can easily compute a histogram associated with a particular data. One of the most commonly used software for this purpose is Stat-Crunch software.
To generate a histogram in stat-crunch follow these steps;
Enter the data in any column of stat-crunch
Click on Graph followed by Histogram
Select the column that contains your data
Click compute
Stat-Crunch generates the histogram as shown in the attachment below.
