Answer:
the answer is B, 500 per week and 12 in tips for a total equal to or greater than 800 dollers
Answer:
Step-by-step explanation:
Given Parameters
Mean,
= 180
total samples, n = 20
Standard dev,
= 30
= 1 - 0.95 = 0.05 at 95% confidence level
Df = n - 1 = 20 - 1 = 19
Critical Value,
, is given by

a).
Confidence Interval,
, is given by the formula



b).
Critical Value,
, is given by

Confidence Interval,
, is given by


= 180 +/- 14.0403
= 165.9597 <
< 194.0403
B.) 14/43
1&2 =7+7
= 14
Bottam:
14 + 8 +6 + 9 +6
= 43
Lastly
= 14/43
P(Greece) =0.28 among tem P(G∩I) = 0.11. We also know tat
P(G ∪ I ) =1 [either Greece or Italy or both= all travelers)
The only data that is missing is te P(Italy)
P(G ∪ I ) = P(G) + P(I) - P(G∩ I)
1 =0.28 + P(I) so P(I) = 0.72
P(G) = 0.28 (including the 0 .11)
P(I) = 0.72 (including the 0.11)
P(G and I) =0.11
Answer:
-22
Step-by-step explanation:
Plug in 5 for x.
y = -3(5) - 7
y = -15 - 7
y = -22
