Answer:
Pvalue = 0.063008
Step-by-step explanation:
Given :
Sample size, n = 63
The test statistic = - 1.53
To test if average room price is significantly different from $110 ; μ = $110
H0 : μ = 110
H1 : μ < 110
From the test statistic value obtained, we could see that the test is left tailed
The Pvalue :
P(Z < - 1.53) = 0.063008
If the claim is to be tested at 5% level of confidence then
Pvalue > 0.05 ; Hence, we fail to reject the. NULL. Hence, average price is not significantly different from $110
Answer: Let E be the event that the first marble selected is green. Let F be the event that the second marble selected is green. A box contains 20 blue marbles, 16 green marbles and 14 red marbles P(F/E)=15/49 because if the first marble selected is green there are 49 in total and 15 are green. I think this is it.
Step-by-step explanation:
Place the compasses on the given external point R.
Answer:
<XYZ = 117°
<XYW+ WYZ = 117°
(6x+44)+(-10x+65)= 117°
6x+44-10x+65= 117°
-4x+ 109= 117°
-4x= 117-109
-4x= 8
x= 8/-4
x= -2
<XYW= 6x+44= 6×-2+44= -12+44= 32°
<WYZ= -10x+65 = -10×-2+ 65= 20+65= 85°
