Wouldn't it be y = | x |? I am not 100% positive but I'm pretty sure that you need to have a least one value. Again not 100% sure
Answer:
C
Step-by-step explanation:
Answer:
The probability that the sample proportion will differ from the population proportion by less than 6% is 0.992.
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 information provided is:
As the sample size is large, i.e. <em>n</em> = 276 > 30, the Central limit theorem can be used to approximate the sampling distribution of sample proportion.
Compute the value of as follows:
Thus, the probability that the sample proportion will differ from the population proportion by less than 6% is 0.992.
Answer:
(12 + n/3) = 2n + 1
Step-by-step explanation:
(12 + n/3) = 2n + 1
36 + n = 6n + 3
33 = 5n
n = 33/5
