From a random sample of 81 dates, the mean record high daily temperature in a certain city has a mean of 83.54°F. Assume the population standard deviation is14.68°F. This creates a 95% confidence interval for the population mean of (80.34, 86.74). Does it seem possible that the population mean could be less than 85°F?Explain.Choose the correct answer below.O A. No, it does not seem possible because 85°F is greater than the right endpoint of the confidence interval.O B. No, it does not seem possible because 85°F is less than the left endpoint of the confidence interval.O C. Yes, it seems possible because 85°F is between the endpoints of the confidence interval.O D. Yes, it seems possible because 85°F is greater than the right endpoint of the confidence interval.

The reading speed of second grade students in a large city is approximately normal, with mean of 91 words per minute (wpm) and a standard deviation of 10 wpm. Complete parts (a) through (f). O B. If 100 different students were chosen from this population, we would expect to read exactly 95 words per minute. O C. If 100 different students were chosen from this population, we would expect to read less than 95 words per minute. (b) What is the probability that a random sample of 13 second grade students from the city results in a mean reading rate of more than 95 words per minute? The probability is 0.0746. (Round to four decimal places as needed.) Interpret this probability. Select the correct choice below and fill in the answer box within your choice. O A. If 100 independent samples of n = 13 students were chosen from this population, we would expect sample(s) to have a sample mean reading rate of exactly 95 words per minute. O B. If 100 independent samples of n = 13 students were…

A research scientist wants to know how many times per hour a certain strand of bacteria reproduces. The mean is found to be 7.8 reproductions and the population standard deviation is known to be 2.2 If a sample of 697 was used for the study, construct the 85% confidence interval for the true mean number of reproductions per hour for the bacteria.

A community college Math instructor feels that the average age of community college students decreased since they started teaching 25 years ago. Looking up data from the year the instructor started teaching, the mean age of community college students was 24.3 years old, with a population standard deviation of 2.2 years. The Math instructor took a sample of 40 of their current community college students and found that the sample had a mean age of 23.7 years old. Assume the population of ages of community college students is normally distributed and that the population standard deviation has remained the same. Test at the 5% significance level if the mean age of community college students is now less than 24.3 years old. The question is attached.

The metropolitan airport commission is considering the establishment of limitations on noise pollution around a local airport. At the present time, the noise level per jet takeoff in one neighborhood near the airport is approximately Normally distributed with a mean of 100 decibels and a standard deviation of 6 decibels. (a) What proportion of jets generates a noise level greater than 105 decibels at takeoff in this neighborhood? (b) If six takeoffs are selected at random, what is the probability that at least 2 will generate noise in excess of 105 decibels and at least 2 will not generate noise in excess of 105 decibels? (c) Suppose a regulation is passed that requires jet noise in this neighborhood to be lower than 105 decibels 90% of the time. Assuming the standard deviation of the noise distribution remains the same, how much will the mean level of noise have to be lowered to comply with the regulation?
