The time (in number of days) until maturity of a certain variety of tomato plant is Normally distributed with an unknown mean and standard deviation = 2.4. I select a simple random sample of four plants of this variety and measure the time until maturity. The sample yields * = 65. A 95% confidence interval for u, in days, is: 65.00± 1.97. 65.00 +2.35. 65.00 ± 3.95. 65.00 +4.70.

In a study of morphological variation in natural populations of fruit fly, it was reported that the mean wing length of 16 females, collected in a certain area, was 4.653 mm with s = 0.012 mm; and the mean wing length of 11 females, collected in a second area, was 4.274 mm with s = 0.02. Let the distribution of the wing length be normal, find a 98% confidence interval on the ratio of the two populations’ standard deviations.

A random sample of 46 adult coyotes in a region of northern Minnesota showed the average age to be x = 2.01 years, with sample standard deviation s = 0.72 years. However, it is thought that the overall population mean age of coyotes is μ = 1.75. Do the sample data indicate that coyotes in this region of northern Minnesota tend to live longer than the average of 1.75 years? Use α = 0.01. State the null and alternate hypotheses. H0: μ < 1.75 yr; H1: μ = 1.75 yr H0: μ > 1.75 yr; H1: μ = 1.75 yr H0: μ = 1.75 yr; H1: μ ≠ 1.75 yr H0: μ = 1.75 yr; H1: μ > 1.75 yr H0: μ = 1.75 yr; H1: μ < 1.75 yr (b) What sampling distribution will you use?

The average local cell phone call length was reported to be 2.27 minutes. A random sample of 10phone calls showed an average of 2.98 minutes in length with a standard deviation of 0.98 minute. At alpha= 0.01can it be concluded that the average differs from the population average?
The mean noise level of 19 randomly selected areas designated as emergency rooms was 63.1 dBA and the sample standard deviation is 5.0 dBA. The mean noise level for 24 randomly selected areas designated as operating theaters was 56.3 dBA and the sample standard deviation was 7.0 dBA. An engineer reported a confidence interval of (1.8454, 11.409) for the difference in the mean noise level between areas designated as emergency rooms and areas designated for operating theaters, but neglected to specify the significance level. Estimate the significance level of the confidence interval if the population standard deviations, 01 and oz of the two populations are unknown and unequal. At the estimated significance level, could it be concluded that there is a difference in the means?
