I hope this helps you
x=0 f (0)=0^2+1=1
x=1 f (1)=1^2+1=2
x=2 f (2)=2^2+1=5
x=3 f (3)=3^2+1=10
What do you exactly need help with?
Answer:
1. Formula is A2 : A9 = COUNT( A2: A9 ) = 8
2. Formula is SUM( A2: A9 ) = 36
3. Formula is B2 : B9 = COUNT( B2: B9) = 8
4. Formula is MAX( C2: C9) = 5
5. Formula is MIN( C4: C8) = 3
6. Formula is SUM( C5 - C6) = 0
7. Formula is AVERAGE( C2: C9) = 4

Answer:
4/24
Step-by-step explanation:
Answer:
(a) 95% confidence interval for the percent of all adults who want to lose weight is (48%, 54%) that is between 48% and 54%
(b) to say that we have 95% confidence in this interval means that there is 95% chance that the true percentage of all adults who wants to lose weight falls in this interval.
Step-by-step explanation:
The question is missing, complete question is below:
A Gallup Poll found that 51% of the people in its sample said "yes" when asked, "Would you like to lose weight?" Gallup announced: "With 95% confidence for results based on the total sample of national adults, one can say that the margin of sampling error is ± 3%."
(a) What is the 95% confidence interval for the percent of all adults who want to lose weight?
(b) What does it mean to say that we have 95% confidence in this interval?
Confidence Interval can be calculated using p±ME where
- p is the sample proportion of national adults who want to lose weight (51%)
- ME is the margin of sampling error (± 3%)
