In the study from the previous question, x=79 adults have been confirmed hypertensive out of n=167 participants. Assuming the standard normal distribution can be applied and p=0.375 under the null hypothesis, what is the Z-statistic for x=79? Recall that the expected value = np and the standard deviation = .

Question 21 Suppose a health insurance company is interested in carrying out an investigation as to the annual expenditures per household on their healthcare costs. In order to most accurately report their figures, the company decides to ensure “virtual certainty” about their estimates by using a Z value of 3.0 for their calculations. The company conducts a SRS of 843 households and determines the sample average household expenditures on healthcare is $43,257.00. A) Assume the company uses a σ=$879.00. Calculate...

Boomerang Generation: The Boomerang Generation refers to the recent generation of young adults who have had to move back in with their parents. In a 2012 survey, suppose 160 out of 803 randomly selected young adults (ages 18–34) had to move back in with their parents after living alone. In a similar survey from the year 2000, suppose 294 out of 1824 young adults had to move back in with their parents. The table below summarizes this information. The standard...

From previous studies, it has been generally believed that Northern Hemisphere icebergs have a mean depth of 270 meters. An environmentalist has suggested that global warming has caused icebergs to have greater depth. A team of scientists visiting the Northern Hemisphere observed a random sample of 41 icebergs. The depth of the base of the iceberg below the surface was carefully measured for each. The sample mean and standard deviation were calculated to be 276 meters and 20 meters respectively....

TRUE OR FALSE: 1. The sampling distribution of (X-bar) is always a normal distribution according to the Central limit theorem. 4. If the sampled population is a normal distribution, then the sampling distribution of   (X-bar is normal only for a large enough sample size. 5. If p=.8 and n=50, then we can conclude that the sampling distribution of the proportions is approximately a normal distribution. 8. Assuming the same level of significancea, as the sample size increases, the critical t-value...

1. Let x be a continuous random variable. What is the probability that x assumes a single value, such as a (use numerical value)? 2. The following are the three main characteristics of a normal distribution. The total area under a normal curve equals _____. A normal curve is ___________ about the mean. Consequently, 50% of the total area under a normal distribution curve lies on the left side of the mean, and 50% lies on the right side of...
