If we spin the spinner 10 times, what is the best prediction possible for the number of times it will land on yellow or purple?

kiruha [24]

Answer:

Yellow = 5 times and I think you meant blue since there is no purple so blue = 3 times

Step-by-step explanation:

There is ten in all and half of the spaces are yellow, or 50%. Out of ten times, you should land on it about half, or 5. For blue, there are 3 spaces, or 30%. Out of ten times, you should lamd on it about three.

It is reported that 25% of the flights arriving at the Washington Dulles airport in January 2008 were late. Assume the populatio

lawyer [7]

Answer:

$P(0.22$

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The population proportion have the following distribution

$p \sim N(p,\sqrt{\frac{p(1-p)}{n}})$

For this case the standard error is given by:

$SE =\sqrt{\frac{p(1-p)}{n}} =\sqrt{\frac{0.25(1-0.25)}{625}}=0.0173$

Solution to the problem

For this case we want to find the probability that the sample proportion will be within +-.03 of the population proportion like this:

$P(0.25-0.03 < p< 0.25+0.03) =P (0.22$

And for this case we can use the following z score:

$z = \frac{\hat p - p}{SE_{p}}$

And using this formula we got:

$P(0.22$

And we can find this probability like this:

$P(-1.732$

What are the independent and dependent quantities?

Anit [1.1K]

There are two types of variables-independent and dependent. Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.

Hope this helps! :)
