hat a random sample of 60 accounting graduates at a large university who received job offers
resulted in a mean offer of $49,800 and a standard deviation of $3,100. What is the observed significance level?


The correct answer is 0.261, but I'm not sure how to get there.

Answer:

The significance level of difference in fhe two means is indeed 0.26.

Step-by-step explanation:

To obtain the significance level, just standardize the mean in 2012 with the new mean and standard deviation.

The standardized score (z) is the value (x) minus the mean (xbar) then divided by the standard deviation (σ)

z = (x - xbar)/σ = (49007 - 49800)/3100 = - 0.26

Therefore, the significance level of difference is indeed 0.26.

Ostrovityanka [42]

Answer:

\displaystyle 25°\:and\:°65

Step-by-step explanation:

{90° = m∠1 + m∠2

{105° = 2m∠1 - m∠2

_______________

\displaystyle \frac{195°}{3} = \frac{3m∠1}{3} \\ \\ 65° = m∠1

All you have left to do is this:

\displaystyle 25° = -65° + 90°

So, your two angle measures are \displaystyle 25°\:and\:°65.

Find the length of the indicated side.
Ne4ueva [31]

Hello

DEF and IKL , equilateral  =>

DE = 5x-12 = 3x-4

5x-3x= -4+12

2x= 8

x=4

DE = 5x-12 =  20-12 = 8

KL = 3x+24 = 10x+3

24 -3 = 10x-3x

21 = 7x

x= 21/7 = 3

KJ = 10x+3 = 30+3 = 33

Greater than symbol is ">"
But since he mentioned "NO greater than" then it's the opposite of greater than, which means "K" is less than "9"
