Answer: ( 77.27 , 83.93)
Therefore at 95% confidence/prediction interval is
= ( 77.27 , 83.93)
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 = 80.6 words per minute
Standard deviation r = 7.2
Number of samples n = 18
Confidence interval = 95%
z(at 95% confidence) = 1.96
Substituting the values we have;
80.6+/-1.96(7.2/√18)
80.6+/-1.96(1.697056274847)
80.6 +/- 3.33
= ( 77.27 , 83.93)
Therefore at 95% confidence/prediction interval is
= ( 77.27 , 83.93)
So for each day, Tessa ran 2.25 miles. So, multiply 2.25 miles by the number of days, which is 14, to get the total number of miles ran.
2.25 x 14 = 31.5 miles
Answer:
1.02
Step-by-step explanation:
The value of the boolean variable x is 0
<h3>How to determine the value of x?</h3>
The boolean equation is given as:
x . 1 = 0
The above means that:
x and 1 = 0
The law of the and operator is that;
The output is 0 if both inputs are different.
One of the inputs is 1.
So, the other input is 0
Hence, the value of x is 0
