All possible random samples of 200 middle managers are selected from a population for a study concerning their mean annual income. The population standard deviation is computed to be $2,248.5. What is the standard deviation of the sampling distribution of the means?

Answers

Answer:

158.993

Step-by-step explanation:

We have to find the standard deviation of the sampling distribution of the means.

We are given that population standard deviation=σ=2248.5 and sample size=n=200.

Standard deviation of sampling distribution of  means=σxbar=σ/√n

σxbar=2248.5/√200

σxbar=2248.5/14.1421

σxbar=158.993

Thus, the standard deviation of the sampling distribution of the means is $158.993.

14.4% of what number is 10.4

Answers

First, convert "of" to x and put this info into an equation:

Let n represent the unknown number.  

14.4 % x n= 10.4
              n = 10.4 / 14.4%
              n = 72.22222
              n = ~72

Answers

Answer:

F = (9C + 32)/(5)

Step-by-step explanation:

Given

C = ((5F - 32))/(9)

Required

Determine the inverse function

C = ((5F - 32))/(9)

Make F the subject of formula:

Multiply through by 9

9C = 5F - 32

Add 32 to both sides

9C + 32= 5F

Divide through by 5

(9C + 32)/(5)= F

F = (9C + 32)/(5)

The inverse function is °F = (9/5 * °C) + 32.

To determine this inverse function, we first need to understand that it's the reverse conversion from Celsius to Fahrenheit. In the original conversion from Fahrenheit to Celsius, we subtracted 32 from the Fahrenheit temperature and then divided the result by 9/5 (or 1.8).

To find the inverse, we need to do the opposite operations in reverse order. First, we need to undo the division by 1.8, which is equivalent to multiplying by 5/9. Then, we need to undo the subtraction of 32 by adding 32 to the result.

This process is different from determining previous inverses because it involves reversing the operations in the opposite order and with different constants (5/9 and 32) compared to the original function.

The F and °C variables need to be switched in the inverse function because we are now going from Celsius to Fahrenheit, and the relationship between these temperature scales requires different mathematical operations.

Switching them makes sense because it aligns with the real-world relationship between the two temperature scales and ensures that the inverse function correctly converts from Celsius to Fahrenheit
