Research has shown that early onset of hearing loss can be attune to prolonged, intense exposure to music at impacting decibels from headphones and rock concerts. In order to test this relationship, researchers enrolled a group of 25-35 year olds and followed them for 15 years, asking participants to document their music listening habits in a journal that would be regularly checked by the research professionals. The journals would be interpreted and an overall average exposure level over a specified period of time would be quantified into four quartiles based on decibel strength of the music experience the participant endured. Signs or symptoms of early hearing loss would be dichotomized into either expressing a decreased hearing capability or not based on an examination at the end of the study. The following partially filled table represents the results of the study. Hearing Loss No Hearing Loss Total Decibel Strength (0-60) - non expose 29 85 114 Decibel Strength (61-100) -2nd lowest…
Consider that we are interested in computing the time weighted average number of cars parked in the parking garage on a Sunday in December. We start at midnight and collect the entry and exit times of cars in the garage until the following midnight as follows. Entry 12:45:00 AM Entry 1:00:00 AM Entry 3:30:00 AM Exit 5:15:00 AM Entry 7:00:00 AM Entry 8:15:00 AM Exit 8:45:00 AM Entry 10:00:00 AM Exit 10:30:00 AM Entry 2:30:00 PM Exit 4:15:00 PM Entry 6:00:00 PM Exit 7:45:00 PM Entry 9:30:00 PM Exit 11:15:00 PM What was the time weight average number of cars parked in the parking garage on that Sunday?
In a population-based cohort study, an entire community was interviewed regarding smoking habits and then followed for one year. Upon ascertainment of all lung cancer deaths, the investigator obtained the following data: Number of Individuals Lung Cancer Deaths Smokers 24,500 15 Nonsmokers 10,500 2 Calculate the risk difference per 100,000 per year.

Dr.Blume has trained observers to use frequency recording to record the behavior of 12 schizophrenic clients. According to the analysis of the data κ = 0 . 47, do you think the observers are sufficiently trained to allow Dr. Blume to proceed with the research?
Q.No.1. Read the following passage and observe the word length of each word. Make a frequency distribution of word length. "Statistics play an intrinsic role in computer science and vice versa. Statistics is used for data mining, speech recognition, vision and image analysis, data compression, artificial intelligence, and network and traffic modeling. A statistical background is essential for understanding algorithms and statistical properties that form the backbone of computer science. Typically, statistical approach to models tends to involve stochastic (random) models with prior knowledge of the data. The computer science approach, on the other hand, leans more to algorithmic models without prior knowledge of the data. Ultimately, these come together in attempts to solve problems."

A machine operator is required to reach between the tools of a vertical hydraulic press between each cycle of the press. Under fault conditions, the operator is at risk from a crushing injury due either (a) to the press tool falling by gravity or (b) to an unplanned (powered) stroke of the press. The expected frequencies of the failures that would lead to either of these effects are given in the table below: Frequency (per year) Effect 0.2 a 0.1 0.1 0.05 Failure type Flexible hose failure Detachment of press tool Electrical fault Hydraulic valve failure (i) a b a or b Given that the operator is at risk for 20 per cent of the time that the machine is operating, construct and quantify a simple fault tree to show the expected frequency of the top event (a crushing injury to the operator's hand).
A study was conducted to investigate factors such as diet and environment that may be related to the formation of enteroliths (enteroliths are calcifications that form in the gut of a horse and can cause considerable morbidity and mortality).

A particular paper included the accompanying data on the tar level of cigarettes smoked for a sample of male smokers who subsequently died of lung cancer. Assume it is reasonable to regard the sample as representative of male smokers who die of lung cancer. Is there convincing evidence that the proportion of male smoker lung cancer deaths is not the same for the four given tar level categories at the ? = .05 level? (Use 2 decimal places.)
