Answer:
the answer is 64 im 100% sure
Answer:
a) The margin of error (E) = 2.06
b) Confidence interval (CI) = 32.66±2.06475
==> CI = [30.59 < μ < 34.72]
c) The mean cost of a meal for two in a mid-range restaurant in Tokyo is $40 and the mean cost of a meal for two in a mid-range restaurant in Hong Kong is $32.66. The mean cost in Hong Kong is lesser than the mean cost in Tokyo.
Step-by-step explanation:
a) By margin of error = ±Z*SE
If we compute the SE - Standard error, we have 1.05344 and Z statistics from statistical table is 1.96.
That gave us, 2.06 (2 decimal place)
b) By confidence interval (CI) = μ± margin of error
If we compute mean from the data give, we have 32.66. Thus, the interval is what we have in (b).
c) The mean cost in Honk Kong (whether up or lower value ) is strictly less than the mean value in Tokyo.
Minus 5 from both sides so we have 3a=-19 now divide both sides by 3 so we have a=-6 1/3
8 and 3/10 because the 3 is in the ones place so you make that a fraction which would be 3/10. Then 8 would be a whole number. Hope this helps!
