Answer:
58.9
Step-by-step explanation:
64-(8% of 64)=64-(8/100)×64=64(1-8/100)=
64×92/100=58.88
Rounded to tenth: 58.9
Answer:
The sampling distribution of
is:
.
Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
The standard deviation of this sampling distribution of sample proportion is:

The study was conducted using the data from 15,000 students.
Since the sample size is so large, i.e. <em>n</em> = 15000 > 30, the central limit theorem is applicable to approximate the sampling distribution of sample proportions.
So, the sampling distribution of
is:
.
Answer:
Step-by-step explanation:
the slope equation is (y2-y1)/(x2-x1)
