Answer:
it is 10,000
Step-by-step explanation:
Multiply the fraction by both things in the parenthesis.
Since we are not given any information about the proportion, we will assume the sample proportion to be 0.50
so,
p = 0.50
The Error is 10% percentage point. This means that on either side of the population proportion the error is 5% so E = 0.05
z = 1.645 (Z value for 90% confidence interval)
The margin of error for population proportion is calculated as:
This means 271 students should be included in the sample
16:30
16/30
16 to 30
is the ratio of girls to the classmembers
Hope this helps!
The LCM is of 128 and 32 is 128
