Answer:
150%
Step-by-step explanation:
this is because you can make a part to whole ratio where you have x/100 (which would symbolize the percent) and 160/40 (which would symbolize the part) then, multiply 160 by 100 to get 16000 and then divide by 40 to fulfill the x. Hope this helps!
Answer:
No, binomial distribution cannot be applied.
Step-by-step explanation:
We known that a Binomial Distribution depends on provided experiment , a binomial distribution have only 2 outcomes. For example, when we flip a coin in the air, then the possible outcomes are Head and Tail.
But in the context, an American roulette wheel has outcomes. It means when we spin the American Roulette wheel, ball may lend on any of the numbers between 0 to 36. So there are more than outcomes.
Therefore, binomial distribution can not be applied here.
Answer:
a) n = 100
s = 8
Confidence interval = 95%
Z at 95% = 1.96
Confidence interval formula : to
Substitute the values :
Confidence interval : to
Confidence interval : to
b)n = 200
s =11
Confidence interval = 90%
Z at 90% = 1.64
Confidence interval formula : to
Substitute the values :
Confidence interval : to
Confidence interval : to
