if fifty cents is divided equally among three friends there will be some cents left how many cents will be left
HACTEHA [7]
Greetings!

This can be solved by dividing 50 by 3 (the amount of friends, you're spiting the money with.)

50/3=16.6667

We have to round down in order to get a whole number: 16

16*3=48
50-48=2

If 50 cents is divided equally among three friends, each would get 16 cents and there would be 2 cents left over.

Hope this helps.

In the United States, 36 percent of the people have a blood type that is A positive. From a random sample of 150 people from Nor
djverab [1.8K]

Answer:

The standard deviation used in the test statistic is 0.04.

Step-by-step explanation:

A single proportion <em>z</em>-test can be used to determine whether the proportion of people in Norway with a blood type of A positive is different from that in the United States.

The proportion of people in Norway with a blood type of A positive is 36% or 0.36.

The hypothesis can be defined as:

<em>H₀</em>: The proportion of people in Norway with a blood type of A positive is 36%, i.e. <em>p</em> = 0.36.

<em>Hₐ</em>: The proportion of people in Norway with a blood type of A positive is different from 36%, i.e. <em>p</em> ≠ 0.36.

The test statistic is:

z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}

The information provided is:

<em>p</em> = 0.36

<em>n</em>  = 150

Compute the standard deviation used in the test statistic as follows:

\sigma=\sqrt{\frac{p(1-p)}{n}}

   =\sqrt{\frac{0.36\times (1-0.36)}{150}}

   =\sqrt{0.001536}\\=0.03919184\\\approx 0.04

Thus, the standard deviation used in the test statistic is 0.04.
