A researcher wished to compare the average amount of time spent in extracurricular activities by high school students in a suburban school district with that of high schoolers in a school district of a large city. The researcher obtained an SRS of 60 high school students in a large suburban school district and found the mean time spent in extracurricular activities per week to be x1 = 6 hours, with a standard deviation s1 = 3 hours. The researcher also obtained an independent SRS of 40 high school students in a large city school district and found the mean time spent in extracurricular activities per week to be x2 = 4 hours, with a standard deviation s2 = 2 hours. Let u1 and u2 represent the mean amount of time spent in extracurricular activities per week by the populations of all high school students in the suburban and city school districts, respectively. Assume the two-sample t-procedures are safe to use.
With a level of 5%, test the hypothesis that the amount of time spent on extracurricular activities is no different in the two groups.
For the problem above, a 95% confidence interval for u1-u2 is (use the conservative value for the degrees of freedom)
a. 2 +- 0.5 hours.
b. 2 +- 0.84 hours.
c. 2 +- 1.01 hours.
d. 2 +- 1.34 hours

At a school. Number of boys:number of girls=11:9. There are 124 more boys than girl. Work out the total number of students at the school
Answers
Answer:
Total students = 1240
Step-by-step explanation:
Given that,
Number of boys: number of girls=11:9
[tex]\dfrac{x}{y}=\dfrac{11}{9}\\\\9x=11y[/tex] ......(1)
There are 124 more boys than girls i.e.
x = 124+y .....(2)
Put the value of x from equation (2) in equation (1). So,
9(124+y) = 11y
1116 +9y = 11y
1116 = 2y
y = 558
Put the value of y in equation (2).
x = 124+558
x = 682
Total students = x+y
= 682+558
= 1240
So, there are 1240 students at the school.

A unit conversion is done to express the same property as a different unit of measurement.
As per the question ;
Some measures i.e., 90 centimeters, 40 meters, 30 kilometers, 10 meters, 40 millimeters are given.
Let's check which is the longest by converting them all in same units say centimeters.
So ;
a) 90 centimeters
= 90 centimeters
b) 40 meters
= 40 × 100 centimeters
= 4000 centimeters
c) 30 kilometers
= 30 × 1000 meters
= 30000 × 100 centimeters
= 3000000 centimeters
d) 10 meters
= 10 × 100
= 1000 centimeters
e) 40 millimeters
= 40 / 10 centimeters
= 4 centimeters
So ; the longest is 30 kilometers.
Thus , the longest measure from the given measures is 30 kilometers.
