Please brake down why !

lana66690 [7]

Answer:

Step-by-step explanation:

using the rule of radicals

• $\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

simplifying $\sqrt{32}$

$\sqrt{32}$ = $\sqrt{16(2)}$ = $\sqrt{16}$ × $\sqrt{2}$ = 4 $\sqrt{2}$

$\sqrt{32}$ + 5 $\sqrt{2}$

= 4 $\sqrt{2}$ + 5 $\sqrt{2}$ = 9 $\sqrt{2}$ → D

Which is a positively skewed distribution

Ede4ka [16]

Answer:

Choice C

Step-by-step explanation:

A and B represent symmetric distributions, that is most data values lie in the middle and the both tails are equally longer.

C represents a positively skewed distribution, most of the data values lie to the left with a few points skewing the shape of the distribution to the right.

Assume that the population proportion is 0.56. Compute the standard error of the proportion, σp, for sample sizes of 100, 200, 5

Aliun [14]

Answer:

Standard errors are 0.049, 0.035, 0.022, and 0.016.

Step-by-step explanation:

The given value of population proportion (P) = 0.56

Given sample sizes (n ) 100, 200, 500, and 1000.

Now standard error is required to calculate.

Use the below formula to find standard error.

When sample size is n = 100

$\sqrt{\frac{P(1-P)}{n}} = \sqrt{\frac{0.56(1-0.56)}{100}} =0.049$

When sample size is n = 200

$\sqrt{\frac{P(1-P)}{n}} = \sqrt{\frac{0.56(1-0.56)}{200}} = 0.035$

When sample size is n = 500

$\sqrt{\frac{P(1-P)}{n}} = \sqrt{\frac{0.56(1-0.56)}{500}} =0.022$

When sample size is n = 1000

$\sqrt{\frac{P(1-P)}{n}} = \sqrt{\frac{0.56(1-0.56)}{1000}} = 0.016$
