how many weeks of data must be randomly sampled to estimate the mean weekly sales of a new line of athletic footwear? We want 98
Ber [7]

Answer:

We need to sample at least 37 weeks of data.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.98}{2} = 0.01

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.01 = 0.99, so z = 2.327

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

We want 98% confidence that the sample mean is within $500 of the population mean, and the population standard deviation is known to be $1300

This is at least n weeks, in which n is found when M = 500, \sigma = 1300

So

M = z*\frac{\sigma}{\sqrt{n}}

500 = 2.327*\frac{1300}{\sqrt{n}}

500\sqrt{n} = 2.327*1300

\sqrt{n} = \frac{2.327*1300}{500}

(\sqrt{n})^{2} = (\frac{2.327*1300}{500})^{2}

n = 36.6

Rounding up

We need to sample at least 37 weeks of data.

andriy [413]

Answer:

C. After gaining independence, territory in both former colonies was divided due to religious conflicts

Step-by-step explanation:

The British had India as their colony, and Palestine as their mandate. Once the World War II ended though, the British saw that they are not in a financial position to be able to keep their colonies and mandates, so they decided to grant them independence. The independence didn't went as desired by the locals though, as both India and Palestine got partitioned because of religious reasons. India was partitioned into Hindu and Muslim part, while Palestine and Muslim and Jewish part. The situation in the Indian subcontinent quickly escalated, as well as in Palestine where the Arabs saw the formation of Israel as stealing of their land.
