When it comes to statistics, a confidence interval (CI) is a type of interval estimate of a population parameter. Statistics is all about drawing conclusions in the face of uncertainty. Whenever you take a sample, you can’t be completely certain that your sample truly reflects the population it’s drawn from.
In conclusion, from the choices presented, the best option is the last one. Option D.
You have 4 options:
4 cards: because you draw cards and don't replace them your chance p changes on every trial, so it can't be a binomial experiment
roll 2 dice until...: a binomial experiment must have a consistent amount of trials, by doing an action until some condition is fulfilled violates this as the amount of trials or throws in this case is random
ask 9 people: there are three options, binomial experiments can only have 2
the only option left is the spinner, which is a binomial experiment
Answer:
y = 3x -5
Step-by-step explanation:
y = mx + b
for (5, 10)
b = y - mx = 10 - 3 x 5 = - 5
y = 3x -5
for (2,1)
check: 1 = 2 x 3 -5
Answer:
