In a recent poll, 300 people were randomly sampled, and 90% said they liked dogs. Use the Theory-Based Inference applet to find a 95% confidence interval for the true population proportion of people who like dogs, T. (a) We are 95% confident that the proportion of all people who like dogs is between 9 % and % Give your percentage answers rounded to one decimal place. For example, if the applet gives (0.34218, 0.61352) then you would enter 34.2 and 61.4. (b) The sample statistic is 0.9 Give your answer as a dEnter an integer or decimal number [more.Jo not round. (c) The margin of error is 0.024 Give your answer as a decimal using your answers form parts (a) and (b). (d) The confidence interval from part (c) can be written as ± Give your answers as decimals (NOT percentages), and do not round.

Question
![In a recent poll, 300 people were randomly sampled, and 90% said they liked dogs. Use the Theory-Based Inference applet to find a 95% confidence interval for the true population proportion of people who like dogs, π.
(a) We are 95% confident that the proportion of all people who like dogs is between [textbox: 9]% and [textbox: 92.4]%
- *Give your percentage answers rounded to one decimal place.*
For example, if the applet gives (0.34218, 0.61352) then you would enter 34.2 and 61.4.
(b) The sample statistic is [textbox: 0.9].
- *Give your answer as a decimal (not a percentage), and do not round.*
(c) The margin of error is [textbox: 0.024].
- *Give your answer as a decimal using your answers from parts (a) and (b).*
(d) The confidence interval from part (c) can be written as
[textbox] ± [textbox]
- *Give your answers as decimals (not percentages), and do not round.*](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5e97558d-4144-4bae-9220-6135476b2bde%2Ff58e0b72-b590-4d08-b8f8-c0719e90d24d%2Fu5z5xbo_processed.png&w=3840&q=75)
