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;
Substitute all the values in the formula
Hence, the value of alpha is 0.26, assuming a confidence level of 74%.

Let's the name the first number x and the consecutive number x + 1. The sum of both of these numbers equals to 53.
We now have our equation:
x + x + 1 = 53
Now solve for x.
x + x + 1 = 53
2x + 1 = 53 <-- Combine like terms
2x = 52 <-- Subtract 1 from each side
x = 26
So, the first number is 26 and the second number is 27.
Answer:
1 : 3
Step-by-step explanation:
Given the following :
First day :
Patient received = 24
Patient discharged = 6
Second day :
Patient received = 8
Patient discharged = 21
First day :
Patient received = 9
Patient discharged = 6
Number of patient in the hospital at the end of the third day:
Patients received = (24 + 8 + 9) = 41
Patients discharged = (6 + 21 + 6) = 33
Patient received - patient discharged
= (41 - 33) = 8
Number of patients in hospital at the start of the three day period :
Patient received on first day = 24
Patient at the end : patient at the start
8 : 24 = 1 : 3
What model? also it would be 1/2 and 1/3
Answer:
40.5g of salt is left after evaporating all the water.
Step-by-step explanation:
Here, 9% of 450g means that out of 450 gram of solution, 9% is the salt.
So, we need to calculate 9% of 450
i.e. 9% * 450 = 0.09 * 450 = 40.5g
Hence, 40.5 grams of salt is in 450 grams of solution.
i.e. 40.5g of salt is obtained after evaporating all the water from the solution.
