Answer:

Read this :)

Step-by-step explanation:

Uniform distributions are probability distributions with equally likely outcomes. In a discrete uniform distribution, outcomes are discrete and have the same probability. In a continuous uniform distribution, outcomes are continuous and infinite. In a normal distribution, data around the mean occur more frequently.

The estimate of the population proportion should be within plus or minus 0.02, with a 90% level of confidence. The best estimate

Rudiy27

Answer:

The sample size required is 910.

Step-by-step explanation:

The confidence interval for population proportion is:

$CI=\hat p\pm z_{ \alpha /2}\sqrt{\frac{\hat p(1-\hat p)}{n} }$

The margin of error is:

$MOE=z_{ \alpha /2}\sqrt{\frac{\hat p(1-\hat p)}{n} }$

Given:

$\hat p = 0.16\\MOE= 0.02\\Confidence\ level =0.90$

The critical value of z for 90% confidence level is:

$z_{\alpha /2}=z_{0.10/2}=z_{0.05}=1.645$ *Use a standard normal table.

Compute the sample size required as follows:

$MOE=z_{ \alpha /2}\sqrt{\frac{\hat p(1-\hat p)}{n} }\\0.02=1.645\times \sqrt{\frac{0.16(1-0.16)}{n} }\\n=\frac{(1.645)^{2}\times 0.16\times (1-0.16)}{(0.02)^{2}} \\=909.2244\\\approx910$

Thus, the sample size required is 910.

75% of a number is 120. What is 40% of the number? A. 36 B. 64 C. 138 D. 225

kakasveta [241]

Answer:

B.64

Step-by-step explanation:

75% of a number is 120.

Let's take "x" be the number.

75% of x = 120

75/100 * x = 120

0.75x = 120

x = 120/0.75

x = 160

So the number is 160.

Now we have to find the 40% of the number 160.

= 40/100 * 160

= 0.4 *160

= 64

40% of the number is B.64

Thank you.
