Find a 92.9% confidence interval for the difference p1−p2p1−p2 of the population proportions.

Hint: For a level of confidence (1−α)⋅100%(1−α)⋅100%, z∗z∗ is the value that leaves an area of (1−α)/2(1−α)/2 to its right in a standard normal distribution

I hope that helps

Which expression is equivalent to \left(3^{-6}\times 3^{3}\right)^{-1}\normalsize?(3 −6 ×3 3 ) −1 ? 3^{-19}3 −19 3^{18}3 18 3^{-

mars1129 [50]

Answer:

Step-by-step explanation:

Given the expression

$\left(3^{-6}\times 3^{3}\right)^{-1}\\$

According to law of indices, this can be written as;

$\left(3^{-6+3})^{-1}\\\\= (3^{-3})^{-1}\\\\= 3^{-3*-1}\\\\= 3^3\\\\= 27$

Hence the required answer is 27

A and b are positive integers and a−b=2. Evaluate the following: 3^b/3^a

Lerok [7]

Answer:

The answer is 1/9.

Step-by-step explanation:

Using the equation a-b=2, we can solve that a = 2+b.

We can then substitute that into the expression given to get 3^b/3^(2+b).

Since they have the same base, we can subtract the exponents from the numerator and denominator to get 3^(b-2-b) which simplifies to 3^-2.

3^-2 is simply 1/9.
