For large sample confidence intervals about the mean you have:
xBar ± z * sx / sqrt(n)
where xBar is the sample mean z is the zscore for having α% of the data in the tails, i.e., P( |Z| > z) = α sx is the sample standard deviation n is the sample size
We need only to concern ourselves with the error term of the CI, In order to find the sample size needed for a confidence interval of a given size.
z * sx / sqrt(n) = width.
so the z-score for the confidence interval of .98 is the value of z such that 0.01 is in each tail of the distribution. z = 2.326348
The equation we need to solve is:
z * sx / sqrt(n) = width
n = (z * sx / width) ^ 2.
n = ( 2.326348 * 6 / 3 ) ^ 2
n = 21.64758
Since n must be integer valued we need to take the ceiling of this solution.
n = 22
Answer:
(-∞ 2] ∪ [-4/3 ∞ )
Step-by-step explanation:
Given compound inequality,
( Subtraction property of inequality )
( Division property of inequality )
( a < b ⇒ - a > - b )
Hence, the solution of the given inequality is,
(-∞ -2] ∪ [-4/3 ∞ )
Answer:
To a power, elevated to something
