The value of alpha is 0.26, assuming a confidence level of 74%.

<h3>What is the margin of error?</h3>

The significance level α is the probability of making the wrong decision when the null hypothesis is true.

Alpha levels which is also called as significance levels are used in hypothesis tests.

Given

When finding the margin of error for the mean of a normally distributed population from a sample.

The confidence interval = 74% = 0.74.

The value of the alpha is given by;

\rm \alpha =1- Confidence \ interval

Substitute all the values in the formula

\rm \alpha =1- Confidence \ interval\\\\\alpha=1-0.74\\\\\alpha=0.26

Hence, the value of alpha is 0.26, assuming a confidence level of 74%.

Reika [66]

Answer:

The solution to the equation x³ - 3x = 1 is given as :

1.88

Step-by-step explanation:

In the above question, we are given the equation

x³ - 3x = 1 ... Equation 1

and we are told the answer lies between 1.8 - 1.9

Using the trial and improvement method approximating to 2 decimal places

a. First trial we use 1.84 for x in equation 1

1.84³ - 3×1.84 = 0.71

This first trial using 1.84 too small

b. Second trial we use 1.86 for x in equation 1

1.86³ - 3×1.86 = 0.86

This second trial using 1.86 as well is too small

c. For our third trial we use 1.89 for x in equation 1

1.89³ - 3×1.89 = 1.08

This third trial using 1.89 is large. Our target is 1.00

d. Our fourth trial we use 1.88 for x in equation 1

1.88³ - 3×1.88 = 1.004

Approximately to 2 decimal places.

We have = 1.00

Hence the solution to the equation

x³ - 3x = 1 after using the trial and improvement method is 1.88
