Product property of square roots: 
<span>For all positive real numbers a and b, the square root of the product is the same as the product of the square roots: </span>
<span>√a * √b = √ab </span>
<span>example: </span>
<span>√3 * √2 = √(3 * 2) = √6 </span>

<span>Quotient property of square roots: </span>
<span>For all positive real numbers a and b, b ≠ 0: the square root of the quotient is the same as the quotient of the square roots: </span>
<span>√a / √b = √a/b </span>
<span>example: </span>
<span>√5 / √3 = √5/3 </span>

Of the 16,071 degrees in mathematics given by U.S colleges and universities in the most recent year, 73% were bachelor's degrees
Alenkasestr [34]

Answer:

The correct answer is 0.4559.

Step-by-step explanation:

Number of degrees in mathematics given by U.S colleges and universities in the most recent year = 16,071

73% were bachelor's degrees= 73% of 16071 = 11731

Women who earned the bachelor's degree = 48% of 11731 = 5630

21% were master's degrees= 21% of 16071 = 3374

Women who earned the masters's degree = 42% of 3374 = 1417

The rest degree were doctorates= 16071 - 11731 - 3374 = 966.

Women who earned the doctorates degree = 29% of 966 = 280

Total number of women who got mathematics degree = 280 + 1417 + 5630 = 7327.

We need to choose a mathematics degree at random and  find the probability that it was awarded to a woman

Probability = \frac{7327}{16071} = 0.4559

Darina [25.2K]

Answer:

p-value (0.0208) is less than alpha = 0.05 reject H0.

Step-by-step explanation:

we have the following data:

sample size = n = 75

x, the number to evaluate is 45

the sample proportion would be: x / n = 45/75

p * = 0.6

Now, the null and alternative hypotheses are:

H0: P = 0.72

Ha: P no 72

two tailed test

statistic tes = z = (p * - p) / [(p * (1-p) / n)] ^ (1/2)

replacing we have:

z = (0.6 - 0.72) / [(0.72 * (1-0.72) / 75)] ^ (1/2)

z = -2.31

p-vaule = 2 * p (z <-2.31)

using z table, we get:

p-vaule = 2 * (0.0104)

p-vaule = 0.0208

Therefore, p-value (0.0208) is less than alpha = 0.05 reject H0.
