7 0

The result from the hypotheis test below shows that there is no significant evidence existing to show difference in the mutation.

<h3>How to solve for the z statistics</h3>

The hypothesis for this test has been stated below:

H0: pI - pII = 0

Ha: pI - pII ≠ 0

n1 = 9

p1 = 0.6%

n2 = 12

p2 = 1%

Using the z statistics formula

\frac{0.006-0.01}{\sqrt{0.000663+0.000825} } \\\\\frac{-0.004}{\sqrt{0.001488} }

z = -0.103

p value = z(-0.103) = 0.4589

The pvalue is greater that 0.01

The decision is to fail to reject the null hypothesis.

There is no significant evidence to show that there is a difference in the prevalence of mutation.

What happens to the composition of an atom to cause it to become positively or negatively charged?
kap26 [50]
An atom is neutral when the number protons and electrons are equal, so when either of these two are taken away or added it will change the charge of an atom. If protons are added or electrons are taken away, a once neutral object will be positive. But if protons are taken away or electrons are added to a once neutral atom, the charge will become negative. Usually electrons are the ones that move and change the atoms charge.
