Answer: ( 8.11 , 9.69)
the 95% confidence interval of the true mean weight
= ( 8.11 , 9.69)
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 = 8.9
Standard deviation r = 0.9
Number of samples n = 5
Confidence interval = 95%
z(at 95% confidence) = 1.96
Substituting the values we have;
8.9+/-1.96(0.9/√5)
8.9+/-1.96(0.4025)
8.9+/- 0.79
= ( 8.11 , 9.69)
Therefore at 95% confidence interval (a,b) = ( 8.11 , 9.69)
Answer:
For Pizza A: 10 + 1.50x
For Pizza B: <u>12.50 + 1.00x</u>
To find the same amount - <u>10 + 1.50x = 12.50 + 1.00x</u>
<u>10 + 0.5x = 12.50</u>
<u>0.5x = 2.50</u>
- With X equally <u>5.</u> 10 + 1.50x + 1.00x = 10 + 2.5x (This may be incorrect)
Step-by-step explanation:
Since you're so desperate...
