In a classic series of studies, solomon asch showed that an individual can conform to a group's judgment of the lengths of lines

Serhud [2]

Based on research studies, in a classic series of studies, Solomon Asch showed that an individual can conform to a group's judgment of the lengths of lines "<u>even when the group judgment was incorrect."</u>

<h3>What is Solomon Asch Conformity Experiment?</h3>

<em><u>Solomon Asch Experiment</u></em> was conducted in 1955 to study the effect of majority or groups on individual beliefs and opinions.

The study's outcomes showed that people would conform with a group, even if they believe or understand it is wrong.

Hence, in this case, it is concluded that the correct answer is <u>"even when the group judgment was incorrect."</u>

Given three consecutive integers, if the sum of the first and third integers is increased by 8, the result is 5 less than triple

Dvinal [7]

We are looking for the value of the second integer, so let's mark it as X.

Then three consecutive integers are : (x-1) , x , (x+1)

The sum of the first and the third integers (X-1) + (X+1)

Five less than three times the second integer 3X - 5

Now we can write an equation and solve it for X

(X-1)+(X+1)= 3X - 5 simplifying left part

2X = 3X -5 subtract 2X from both sides

0 = X-5

X=5

SO THREE CONSECUTIVE INTEGERS ARE 4, 5, 6

elena-s [515]

Answer:

D

Explanation:

Note that the X and Z are the same, so it must be Y=some value.

The plane that works must pass through the midpoint, or (1, 3/2, 3), giving D or y=3/2.

Students in a statistics class are conducting a survey to estimate the mean number of units students at their college are enroll

Andrew [12]

Using the t-distribution, as we have the standard deviation for the sample, it is found that the 95% confidence interval for the number of units students in their college are enrolled in is (11.7, 12.7).

<h3>What is a t-distribution confidence interval?</h3>

The confidence interval is:

$\overline{x} \pm t\frac{s}{\sqrt{n}}$

In which:

$\overline{x}$ is the sample mean.

t is the critical value.

n is the sample size.

s is the standard deviation for the sample.

The critical value, using a t-distribution calculator, for a two-tailed <em>95% confidence interval</em>, with 49 - 1 = <em>48 df</em>, is t = 2.0106.

Hence:

$\overline{x} - t\frac{s}{\sqrt{n}} = 12.2 - 2.0106\frac{1.6}{\sqrt{49}} = 11.7$

$\overline{x} + t\frac{s}{\sqrt{n}} = 12.2 + 2.0106\frac{1.6}{\sqrt{49}} = 12.7$

The 95% confidence interval for the number of units students in their college are enrolled in is (11.7, 12.7).
