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:
If we compare the p value and the significance level given we see that
so we can conclude that we have enough evidence to reject the null hypothesis, so we can conclude that the true mean is higher than 12 at 5% of signficance.
Step-by-step explanation:
Data given and notation
represent the sample mean
represent the population standard deviation for the sample
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
z would represent the statistic (variable of interest)
represent the p value for the test (variable of interest)
State the null and alternative hypotheses.
We need to conduct a hypothesis in order to check if the mean is equal to 12, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
Since we know the population deviation, is better apply a z test to compare the actual mean to the reference value, and the statistic is given by:
(1)
z-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".
Calculate the statistic
We can replace in formula (1) the info given like this:
P-value
Since is a right tailed test the p value would be:
Conclusion
If we compare the p value and the significance level given we see that
so we can conclude that we have enough evidence to reject the null hypothesis, so we can conclude that the true mean is higher than 12 at 5% of signficance.
