You would like to construct a 95% confidence interval to estimate today's population mean temperature, so you make a series of measurements (a random sample) throughout the day. The mean of these measurements is 59 degrees Fahrenheit, and their standard deviation is 4 degrees Fahrenheit.(a) What is the best point estimate, based on the sample, to use for the population mean?☐ degrees(b) For each of the following sampling scenarios, determine which distribution should be used to calculate the critical value for the 95% confidence interval for the population mean.(In the table, \( Z \) refers to a standard normal distribution, and \( t \) refers to a \( t \) distribution.)| Sampling scenario | \( Z \) | \( t \) | Could use either \( Z \) or \( t \) | Unclear ||-----------------------------------------------------------------------------------|---------|---------|------------------------------------|---------|| The sample has size 100, and it is from a non-normally distributed population. | ☐ | ☐ | ☐ | ☐ || The sample has size 16, and it is from a normally distributed population with an unknown standard deviation. | ☐ | ☐ | ☐ | ☐ || The sample has size 110, and it is from a non-normally distributed population with a known standard deviation of 3.9. | ☐ | ☐ | ☐ | ☐ |

You want to obtain a sample to estimate a population mean. Based on previous evidence, you believe the population standard deviation is approximately σ = 43.4 . You would like to be 99% confident that your estimate is within 3 of the true population mean. How large of a sample size is required?
The population standard deviation for the temperature of beers found in Scooter's Tavern is 0.61 degrees. If we want to be 90% confident that the sample mean beer temperature is within 0.1 degrees of the true mean temperature, how many beers must we sample? Round to the nearest beer.
In her class in Statistics, Miss Ped told the students that they need a grade in the top 10% of the class to get an A in a particular test. In the standardization of the test, the mean was 70 and the standard deviation was 12. Assuming that the grades would be normally distributed, what must be the minimum grade needed to obtain an A? Round off answers to the nearest whole number. Blank 1
Scores on the Wechsler Adult Intelligence Scale are approximately normally distributed with 100 and σ=15. Use Table B or software to answer the following questions. What scores fall in the lowest 25% of the distribution? How high a score is needed to be in the highest 5%?
A study on the latest fad diet claimed that the amounts of weight lost by all people on this diet had a mean of 20.4 pounds and a standard deviation of 3.8 pounds. Step 1 of 2: If a sampling distribution is created using samples of the amounts of weight lost by 93 people on this diet, what would be the mean of the sampling distribution of sample means? Round to two decimal places, if necessary.
A population has a mean μ=79and a standard deviation σ=14. Find the mean and standard deviation of a sampling distribution of sample means with sample size n=49. (Simplify your answer.)
[b] Instruction: Solve the following problem: Records show that the performance of male college students in Mathematics in terms of final grade is 5% higher than in female college students with a corresponding standard deviations of 4.35% and 3.97%, respectively. A mathematics instructor verifies this information by having the final grades. There are 80 students, consisting of 44 females and 36 males. The following statistics are shown: Sex Average Final Grade Male 93.45% Female 87.42% Can the mathematics instructor say that the difference between the average final grades obtained by the males and females is higher than 5%? Use 5% level of significance. b. Determine the level of significance and the direction of test.
We want to obtain a sample to estimate a population mean. Based on previous evidence, researchers believe the population standard deviation is approximately σ=26.1. We would like to be 99% confident that the estimate is within 3 of the true population mean. How large of a sample size is required?
Suppose you take a random sample of n = 80 Douglas College students and ask each student their age. You find that the mean age of students in this sample is X = 22.0375 years and the sample standard deviation is s = 3.2014 years. Fill in the blanks (rounding to four decimal places): The 95% confidence interval for the mean age μ of all Douglas College students is from ______ years to ______ years.
