a.) The individual object in the study was a randomly selected This is computer-graded so use exact wording from the problem above. b.) What was the variable information recorded for each object in the study? This is computer-graded so use exact wording from the problem above. c.) State the statistical interpretation of the confidence interval in the context of this problem. Select an answer student is/are between ? ✓ = d.) What is the symbol and value of the point estimate for u? ✓the e.) What is the margin of error for the given interval? A = B = points points Remember: the sample statistic is the midpoint of the confidence interval, and the difference between the highest and lowest value of your interval (its width) is the two times the margin of error. -B- final exam score of ? Harper statistics f.) Fill in the boxes below to show the relation on the number line between the numeric values of the point estimate and the interval estimate for u. C = and

Which of the common confidence levels (90%, 95%, or 99%) would you prefer to use if you wanted to have the smallest confidence interval?

In a survey, 21 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $46 and standard deviation of $15. Construct a confidence interval at a 90% confidence level.Give your answers to one decimal place.

a. 14.0, 16.3, 18.7, 19.9, 21.3       b. 16.1, 13.4, 13.6, 14.9, 14.1, 10.5 Construct the 95% confidence interval for the difference in u of the two given samples.

In a survey, 22 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $38 and standard deviation of $4. Construct a confidence interval at a 90% confidence level.

In a survey, 24 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $36 and standard deviation of $15. Construct a confidence interval at a 90% confidence level.

in a survey, 27 people were asked how much they spent on their child's last birthday gift. the results were roughly bell-shaped with a mean of $30 and sample standard deviation of $20. construct a confidence interval at a 95% confidence level.

a. interpret the corresponding 95% confidence intervals for both Birth weight and Age.  b. What is the predicted average SBP of an infant born with birth weight 8lbs (128oz) measured at 3 days old? c. Calculate the Pearson correlation between Age and Birth weight, and test if this correlation is significant at the 0.05 level. Does this answer surprise you, why or why not?

In a survey, 26 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $33 and standard deviation of $14. Construct a confidence interval at a 90% confidence level.
