According to timeanddate.com the mean temperature in NCR during the dry season is 29°C
with a standard deviation of3.5°C. Temperatures were again observed for a week and the
mean was found to be 32°C. Is there evidence to show that the temperature in NCR has
changed if the level of significance is 1%?

Among 157 patients ,the mean systolic blood pressure was 146 mm Hg with a standard deviation of 27. We wish to know if on the basis of these data, we may conclude that the mean systolic blood pressure for a population is greater than 140. Use a=0.01.

A random sample of 46 adult coyotes in a region of northern Minnesota showed the average age to be x=2.07 years with sample staved deviation s=0.88 years. However, it is thought that the overall population mean age of coyotes is u=1.75.

The population of weights for men attending a local health club is normally distributed with a mean of 172-lbs and a standard deviation of 27-lbs. An elevator in the health club is limited to 33 occupants, but it will be overloaded if the total weight is in excess of 6105-lbs. Assume that there are 33 men in the elevator. What is the average weight per man beyond which the elevator would be considered overloaded?average weight = lbs Round to the nearest pound. What is the probability that one randomly selected male health club member will exceed this weight?P(one man exceeds) = Round to 4 decimal places. If we assume that 33 male occupants in the elevator are a random sample of all male club members, find the probability that the elevator will be overloaded?P(elevator overloaded) = Round to 4 decimal places. If the elevator is full (on average) 2 times a day, how many times do we expect the elevator will be overloaded in one (non-leap) year?number of times overloaded = Round to…
Unfortunately, arsenic occurs naturally in some ground water.† A mean arsenic level of ? = 8.0 parts per billion (ppb) is considered safe for agricultural use. A well in Texas is used to water cotton crops. This well is tested on a regular basis for arsenic. A random sample of 36 tests gave a sample mean of x = 6.9 ppb arsenic, with s = 2.6 ppb. Does this information indicate that the mean level of arsenic in this well is less than 8 ppb? Use ? = 0.01. (a)What is the level of significance? (b)What sampling distribution will you use? Explain the rationale for your choice of sampling distribution. (c)What is the value of the sample test statistic? (Round your answer to three decimal places.)
Suppose the mean pulse rate of college students is 68 beats per minute with a standard deviation of 12.5. You conduct a special exercise program for 31 college students. After completing the program, the mean pulse rate of the students was 63.1. Test the hypothesis that the program lowered students’ pulse rates using  = 0.01.
A brand of lightbulb has an average life of 600 hr, with a standard deviation of 40 hr. The length of life of the bulb can be closely approximated by a normal curve.

The total number of bulbs that can be expected to last less than 708 hr is?
Unfortunately, arsenic occurs naturally in some ground water.† A mean arsenic level of ? = 8.0 parts per billion (ppb) is considered safe for agricultural use. A well in Texas is used to water cotton crops. This well is tested on a regular basis for arsenic. A random sample of 36 tests gave a sample mean of x = 7.1 ppb arsenic, with s = 2.2 ppb. Does this information indicate that the mean level of arsenic in this well is less than 8 ppb? Use ? = 0.01. a) What is the value of the sample test statistic?

The cholesterol levels of an adult can be described by a normal model with a mean of 188mg/dL and a standard deviation of 28. What percent of adults do you expect to have cholesterol levels over 200mg/dL? What percent of adults do you expect to have cholesterol levels between 150 and160mg/dL? Estimate the interquartile range of cholesterol levels.
A random sample of 46 adult coyotes in a region of northern Minnesota showed the average age to be x- 2.03 years, with sample standard deviation s - 0.76 years.
