Answer:
The answer is either (3) or (4) because drawing a line of best fit and finding its gradient is going to give you a negative answer
Answer:
( $74.623, $83.777)
The 90% confidence interval is = ( $74.623, $83.777)
Critical value at 90% confidence = 1.645
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = $79.20
Standard deviation r = $10.41
Number of samples n = 14
Confidence interval = 90%
Using the z table;
The critical value that should be used in constructing the confidence interval.
z(α=0.05) = 1.645
Critical value at 90% confidence z = 1.645
Substituting the values we have;
$79.20+/-1.645($10.42/√14)
$79.20+/-1.645($2.782189528308)
$79.20+/-$4.576701774067
$79.20+/-$4.577
( $74.623, $83.777)
The 90% confidence interval is = ( $74.623, $83.777)

According to the given values, the numbers from least to greatest is ∛64, 4.222.. √19
<h3>Descending and ascending order</h3>
Ordering a sequence of number from least to greatest is known as the ascending order of magnitude
Given the following parameters
∛64, √19 and 4.222...
The cube root of 64 is 4
The square root of 19 is 4.36
While the repeating decimal 4.2. can be 4.2222...
Ordering from least to greatest is 4, 4.2222, 4.36
According to the given values, the numbers from least to greatest is ∛64, 4.222.. √19
