If each pie serves 6 people and there were 22 people at dinner, how many pies exactly, (like a decimal), would feed them?

A social psychologist conducts an experiment and finds a statistically significant result. This means that the a. experiment is

coldgirl [10]

Considering that the hypothesis test found an statistically significant result, it is found that the correct option is:

c. probability of obtaining this finding by chance alone is less than some quantity.

<h3>What is an hypothesis test?</h3>

When a hypothesis test, there are two hypothesis, the null and the alternative hypothesis.

There is also a significance level.

If the probability of obtaining the finding by chance is less than the significant value, the result is statistically significant.

Hence, according to these bullet points, option C is correct.

The 2010 General Social Survey reported a sample where about 48% of US residents thought marijuana should be made legal. If we w

Answer:

The sample size is $n = 600$

Step-by-step explanation:

From the question we are told that

The sample proportion is $\r p = 0.48$

The margin of error is $MOE = 0.04$

Given that the confidence level is 95% the level of significance is mathematically represented as

$\alpha = 100 - 95$

$\alpha = 5 \%$

$\alpha = 0.05$

Next we obtain the critical value of $\frac{\alpha }{2}$ from the normal distribution table , the values is

$Z_{\frac{\alpha }{2} } = 1.96$

The reason we are obtaining critical value of $\frac{\alpha }{2}$ instead of $\alpha$ is because

$\alpha$ represents the area under the normal curve where the confidence level interval ( $1-\alpha$ ) did not cover which include both the left and right tail while

$\frac{\alpha }{2}$ is just the area of one tail which what we required to calculate the margin of error

Generally the margin of error is mathematically represented as

$MOE = Z_{\frac{\alpha }{2} } * \sqrt{ \frac{\r p(1- \r p )}{n} }$

substituting values

$0.04= 1.96* \sqrt{ \frac{0.48(1- 0.48 )}{n} }$

$0.02041 = \sqrt{ \frac{0.48(52 )}{n} }$

$0.02041 = \sqrt{ \frac{ 0.2496}{n} }$

$0.02041^2 = \frac{ 0.2496}{n}$

$0.0004166 = \frac{ 0.2496}{n}$

=> $n = 600$
