Answer:
7.11 * 10^-6
Step-by-step explanation:
Count from decimal = -6 then place to show value 1-9 = 7.11 * 10^-6 The Chaldean were ruled by King Nebuchadnezzar he built one of the Seven Wonders of The World Gardens of Babylon - he also conquered Jerusalem and built a Mesopotamian pyramid called a ziggurat at the center of Babylon including lots of restructure to all cities across the region - Also the rise in culture to design of names for zodiac signs and two pillar scripts as they used astrology and no my name is named after a baby panda lol I realise the Childean's translation for number 9 is Bamboola but i found Bamboola a helpful meaning name considering how people so cry for help with maths- I like to think of these images all while breeding programs are showing remarkable success :-) I am an English girl residing in South East England.

Answer:
Null hypothesis:
Alternative hypothesis:
So the p value is a very low value and using any significance level for example always
so we can conclude that we have enough evidence to reject the null hypothesis, and we can say the the proportion 1 is significantly different from proportion 2.
Step-by-step explanation:
1) Data given and notation
represent the number of people with a characteristic in 1
represent the number of people with a characteristic in 2
sample of 1 selected
sample of 2 selected
represent the proportion of people with a characteristic in 1
represent the proportion of people with a characteristic in 2
z would represent the statistic (variable of interest)
represent the value for the test (variable of interest)
2) Concepts and formulas to use
We need to conduct a hypothesis in order to check if the proportion 1 is different from proportion 2 , the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
We need to apply a z test to compare proportions, and the statistic is given by:
(1)
Where
3) Calculate the statistic
Replacing in formula (1) the values obtained we got this:
4) Statistical decision
For this case we don't have a significance level provided , but we can calculate the p value for this test.
Since is a two sided test the p value would be:
So the p value is a very low value and using any significance level for example always
so we can conclude that we have enough evidence to reject the null hypothesis, and we can say the the proportion 1 is significantly different from proportion 2.
