The phrase which best describes a period on the periodic table is: a row of elements

Periodic table can be defined as an organized tabular arrangement of all the chemical elements arranged in order of increasing atomic number or number of protons, especially in rows.

On a related note, chemical elements with the same number of valence electrons are found in the same column of the periodic table.

In conclusion, the rows of a periodic table are referred to as periods while the columns are referred to as groups.

Let A and B be events with P(A) = 0.61 and P(A ∩ B) = 0.39. For what value of P(B) will A and B be independent?

Answer:

$P(B) = 0.64$

Explanation:

Given

$P(A) = 0.61$

$P(A\ n\ B) = 0.39$

Required

Determine P(B)

If A and B are independent, then:

$P(A\ n\ B) = P(A) * P(B)$

Substitute values for P(A) and P(A n B)

$0.39 = 0.61 * P(B)$

Make P(B) the subject

$P(B) = \frac{0.39}{0.61}$

$P(B) = 0.64$ --- approximated

Answer:

I used the function 1-proportion z-interval on the calculator, where I inputted

Successes(x) = 64
Sample size(n) = 593
Confidence Level(C level) = 0.99

It would result in zInterval_1Prop 64,593,0.99: stat.results, where the values are shown below as:

Lower bound (CLower) = 0.075105
Upper bound (CUpper) = 0.140747
test statistic (p^) = 0.107926
Margin of error (ME) = 0.032821

Therefore, the 99% confidence interval would be around 0.11 ± 0.03 or range from 0.08 to 0.14.

Note: not sure if this is correct O_o
