It would be: 2(p + 1) = 18
= 2p + 2 = 18
= 2p = 18 - 2
= 2p = 16
= p = 16/2
= p = 8
In short, Your Answer would be 8
Hope this helps!
Explanation & work shown in picture.
Make all the x points opposite. For example -837 to +837
Given that the mean is $9.5 and the standard deviation is $1.30, the standard error will be given by:
σ/√n
where
σ-standard deviation
n=sample size
thus, we shal have:
1.30/√20
=0.2906
Next we find the margin error
0.2906*2=0.581
thus the confidence interval will be:
(9.5+0.581, 9.5-0.581)
=(10.081,8.919)
Answer:
13 coffee mugs
Step-by-step explanation:
8.50(13)+2.75(8)
=110.50+2.75(8)
=110.50+22
=132.50
