Unfortunately, arsenic occurs naturally in some ground water.† A mean arsenic level of μ = 8.3 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 41 tests gave a sample mean of x = 7.3 ppb arsenic, with s = 2.4 ppb. Does this information indicate that the mean level of arsenic in this well is less than 8.3 ppb? Use ? = 0.01. (a) What is the level of significance? State the null hypotheses H0 and the alternate hypothesis H1 . H0 : μ ---Select--- < ≥ ≤ = > ≠ H1 : μ ---Select--- < > ≤ ≥ = ≠ (b) What sampling distribution will you use?

Birth weight at a local hospital for the past year had a normal distribution with a mean of 106 ounces and a variance of 36 ounces2. If the middle 50% of the birth weights are considered to have a normal birth weight then what is the birthweight that defines a high birthweight baby (above normal)?
In the general population, IQ scores are normally distributed with a mean of 95 and a standard deviation of 17. You wish to examine whether post-graduates at RMIT have a different level of intelligence than the general population. You sampled 29 RMIT postgraduates and measured their IQ which resulted in a mean of 116 and a standard deviation of 14.4. Calculate Cohen's d. Give your answer to 2 decimal places.
You have developed an exam to measure knowledge of biology and administered it to a large number of people. On this exam, u= 85 and o = 10. You standardize the distribution so that the new mean and standard deviation are u = 50 and o = 5 If someone takes the exam and receives a score of 73 (before the score is transformed), what will this score be once it is transformed for the new (standardized) distribution?
Times for a procedure are normally distributed. There are 2 methods. Method A has a mean of 25 minutes and a standard deviation of 8 minutes. Method B has a mean of 29 minutes and a standard deviation of 4 minutes. Which procedure is preferred if it must be completed within 33 minutes?
Aldo, a highway safety inspector, is concerned about the potential for accidents caused by boulders that fall down a sandstone cliff beside a main highway. As part of an accident simulator, Aldo models the boulders' weights using a normal distribution with a mean of 556 kg and a standard deviation of 100 kg find the percentage of boulders that weigh less than 520kg or more than 592kg according to the model. .
