Answer: the answer to your question is
Recall that when you multiply a decimal by a power of ten (10, 100, 1,000, etc), the placement of the decimal point in the product will move to the right according to the number of zeros in the power of ten. For instance, 4.12 · 10 = 41.2.

Answer:
Because z is higher than any given value in the chart we come to the conclusion To reject null hypothesis
Step-by-step explanation:
Sample proportion = p= 531/648 = 0.8194
This is the proportion of men that were hit by lightening
Null hypothesis: H0: p = 0.5
Alternate hypothesis: H1: p ≠ 0.5
Test statistics z = 0.8194-0.5/(√0.5x0.5/648)
= 0.8194-0.5/√0.0003858
= 0.3194/0.019642
= 16.26
Since the z > 1.96 (at 5% significance) we reject the null hypothesis.
Therefore in conclusion we say z is higher than given values in the chart so we reject null hypothesis.

<span>First, to calculate one tenth of a number, you have to multiply it by .1 or move it one place/spot to the right in the number. The next step would be to identify two number next to each other that are identical. In the number 233,649, the 3 in the 10,000 place and the 3 in the 1,000 place would meet this requirement. As a result, if you were to multiply 30,000 (3 in 10,000 place) by .1 you would get 3,000 (3 in 1,000 place). The answer would be the 10,000 and 1,000 place contain digits that on one tenth the value of each other.</span>
