I am having trouble with these specific questions on estimating a population mean. If I can please receive help, thank you

10: 11: 12: 13: 14: 15: Listed below are the pulse rates of 40 adult males. Construct a condence interval using a 99% condence level. 98487548757544886471 9665876455524371 97 SCI 48 56804881987292577048 8265666593515152 82 The ages of a group of 127 randomly selected adult females have a standard deviation of 16.7 years. Assume that the ages of female statistics students have less variation than ages of females in the general population, so let a = 16.7 years for the sample size calculation. How many female statistics student ages must be obtained in order to estimate the mean within half of a year with 95% condence level. A beverage company uses a machine to ll oneliter bottles with water. Assume that the population of volumes is normally distributed. The company wants to estimate the mean volume of water the mahine is putting in the bottles within one milliliter (ml). Determine the minimum sample size required to construct a 96% condence interval estimate for p. Assume that the population stande deviation is 3 ml. Section 7.3: Estimating a Population Standard Deviation or Variance A sample of 101 body temperatures has a mean of 98.2\"13' and a standard deviation of 0.62F. Construct a 95% condence interval estimate of the standard deviation of the bod}.r temperatures for the entire population. A clinical trial was conducted to test the effectiveness of the drug zopiclone for testing insomnia in older subjects. After treatment with zopiclone, 16 subjects had a mean wake time of 98.9 min and a standard deviation of 42.3 min. Assume that the 16 sample values appear to be from a normally distributed population. Construct a 98% condence interval estimate of the standard deviation of the wake times for a population with zopiclone treatments. The values below are waiting times (in minutes} of customers at the Jefferson Valley Bank, where customers enter a single waiting line that feeds three teller windows. Construct a 95% confidence interval for the population stande deviation 9'. 6.5, 6.6, 6.7, 6.8, 7.1, 7.3, 7.4, 7.7, 7.7, 7.7
