238 students are enrolled in the 7th grade class this year
<u>Solution: </u>
Given that
Percentage decrease in number of students enrolled in 7th grade = 15%
Number of students enrolled last year = 280
Need to determine number of students enrolled in 7th grade this year.
Lets assume number of students enrolled this year = x
<em>Percentage decrease in enrollment </em>= (Number of student enrolled last year – Number of students enrolled this year) whole divided by number of students enrolled last year multiplied by 100
Hence number of students enrolled this year = 238.

Answer:
The range of the 95% data (X) = 238.3 days < X < 289.9 days
Step-by-step explanation:
Given;
mean of the normal distribution, m = 264.1 days
standard deviation, d = 12.9 days
between two standard deviation below and above the mean is 96% of all the data.
two standard deviation below the mean = m - 2d
= 264.1 - 2(12.9)
= 238.3 days
two standard deviation above the mean = m + 2d
= 264.1 + 2(12.9)
= 289.9 days
The middle of the 95% of most pregnancies would be found in the following range;
238.3 days < X < 289.9 days
