Umder what conditions can you use a normal distribution to approximate the binomial distrubution
Shtirlitz [24]

Answer:

See Below

Step-by-step explanation:

A <u>binomial distribution</u> is basically the probability of success of failure of an experiment that is repeated many times.

The parameters are "n" and "p".

Where

n is the number of times the experiment is performed, or the number of trials

p is the probability of success

Note: "q" is the probability of failure, or q = 1 - p

** Binomial Distribution is a discrete distribution

A normal distribution is a continuous distribution that is symmetric about the mean. That means, the data closer to mean occurs more frequently.

At times, we can use normal distribution to approximate a binomial distribution. The conditions can be said as:

<u>" we can approximate a binomial distribution using normal distribution when n is large enough "</u>

How large is large enough?

There isn't a precise answer, but we can take a rule of thumb as

If "n*p" and "n*q" is greater than 10, we can say the sample size, or n, is large enough.

We can approximate when this is less than 10 per say, but the approximation won't be that good. So, the more the value is greater than 10, the better the approximation.

Stefan sells Jin a bicycle for ​$126 and a helmet for ​$17. The total cost for Jin is 130 ​% of what Stefan spent originally to
Marina86 [1]

Answer:

Stefan originally spent $110

Stefen made $33 by selling the bicycle and helmet to jin.

Step-by-step explanation:

let ,

the original cost of bicycle and helmet for Stefan be 'x'

now,

total cost for Jin of bicycle and helmet = 126 + 17

                                                        = 143

also, total cost for Jin = 130% of original cost for Stefan

⇒ 143 = (\frac{130}{100} )x

⇒ x = 110.

hence,

profit made by Stefan = total cost for Jin - original cost for Stefan

                                     = 143 - 110

                                     = 33

If the probability of a chance event is 0.2, it is more likely to happen
densk [106]

Answer:

0.8

Step-by-step explanation:

Things to remember:

- You can add as many 0's on the end of a decimal and it will still equal the same number, as long as the 0's are on the right side of the decimal point. For example, 0.7 = 0.7000.

- The lowest value has the lowest probability

So, let's rewrite the options with the same amount of decimal points:

1.00

0.90

0.80

0.85

Now, find the value under 0.82. In this option, the lowest value is 0.80, and it is under 0.82, so it is the answer.
