**Title: Confidence Interval Estimation of Mean Body Temperature**A data set includes 104 body temperatures of healthy adult humans, having a mean of 98.7°F and a standard deviation of 0.66°F. Construct a 99% confidence interval estimate of the mean body temperature of all healthy humans. What does the sample suggest about the use of 98.6°F as the mean body temperature?- Click here to view a t distribution table.- Click here to view page 1 of the standard normal distribution table.- Click here to view page 2 of the standard normal distribution table.---**What is the confidence interval estimate of the population mean μ?**\[ \_\_\_ °F < μ < \_\_\_ °F \](Round to three decimal places as needed.)**What does this suggest about the use of 98.6°F as the mean body temperature?**- A. This suggests that the mean body temperature is lower than 98.6°F.- B. This suggests that the mean body temperature is higher than 98.6°F.- C. This suggests that the mean body temperature could very possibly be 98.6°F.---*Note: This section is aimed at helping students understand statistical concepts related to confidence intervals and their implications on interpreting mean values in a population.* **POSITIVE z Scores: Cumulative Area from the LEFT**This table shows the cumulative area from the left under a standard normal distribution curve for positive z-scores, indicating the probability of a standard normal random variable being less than a specific z value.**Table Layout:**- **Top row**: Displays the hundredths digit (.00, .01, ..., .09).- **First column**: Displays the tenths digit of z (0.0 to 3.4).**Table Data:**The table provides cumulative probabilities for z-scores from 0.00 to 3.49. For example:- A z-score of 0.0 has a cumulative area of 0.5000.- A z-score of 1.0 has a cumulative area of 0.8413.- A z-score of 2.3 has a cumulative area of 0.9893.Values increase as z increases, showing the cumulative probability of a random variable falling below that z-score.**Graph Explanation:**Above the table, there's a bell-shaped curve representing a standard normal distribution centered at 0. The highlighted area to the left of a positive z value indicates the cumulative probability.**Note:**For z-scores of 3.50 or higher, use 0.9999 for the area.**Common Critical Values:**- .01 (z = 2.33)- .05 (z = 1.645)- .10 (z = 1.282)- .50 (z = 0.0)The table is essential for statistical analysis, particularly in determining probabilities related to the normal distribution.

Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is 63 miles per hour, with a standard deviation of 4 miles per hour. Estimate the percent of vehicles whose speeds are between 59 miles per hour and 67 miles per hour. (Assume the data set has a bell-shaped distribution.) Approximately % of vehicles travel between 59 miles per hour and 67 miles per hour.
The weights of bags of baby carrots are normally distributed, with a mean of 31 ounces and a standard deviation of 0.39 ounce. Bags in the upper 4.5% are too heavy and must be repackaged.

You may need to use the appropriate appendix table or technology to answer this question. The U.S. Energy Information Administration (US EIA) reported that the average price for a gallon of regular gasoline is $2.94. The US EIA updates its estimates of average gas prices on a weekly basis. Assume the standard deviation is $0.25 for the price of a gallon of regular gasoline and recommend the appropriate sample size for the US EIA to use if they wish to report each of the following margins of error at 95% confidence. (Round your answers up to the nearest whole number.) (a) The desired margin of error is $0.10. (b) The desired margin of error is $0.06. (c) The desired margin of error is $0.04.
