The table shows population statistics for the ages of Best Actor and Best Supporting Actor winners at an awards ceremony. The distributions of the ages are approximately bell-shaped. Compare the z-scores for the actors in the following situation. Best Actor Best Supporting Actor H=42.0 μ= 53.0 a=8.5 σ= 12 In a particular year, the Best Actor was 21 years old and the Best Supporting Actor was 56 years old. Determine the z-scores for each. Best Actor: z = Best Supporting Actor: z = (Round to two decimal places as needed.) Interpret the z-scores. unusual. The Best Actor was the mean, which the mean, which unusual.

To chock whether a fly has the mutation, a DNA sequence is analyzed in a way that kills the fly, so the biologist only wants to test a sample of the flies to estimate the proportion of flias that have the mutation. The biologist solocts 40 flies to scquence at random and finds that 9 of them have the genetic mutation. Based on this sample, estimate the proportion of flies in this group that has the gonetic…

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).
In economist studying the job market in Denver area neighborhoods. The X represent the total number of jobs in a given neighborhood, why represent the number of entry-level jobs in the same neighborhood example of six Denver neighborhoods give the following information (units in hundreds of jobs). x 13 30 50 28 50 25 y 1 4 6 5 9 3 given Σx = 196 Σy=28 Σx2=7478 Σy2=168 Σxy = 1098 and r = .9150 a) find x and y Then find the equation of the least squares line y=a+BMX (round your answers to four decimal places) x= y= y=__+__x b) find the value of the coefficient of determination r2. What percentage of the variation in y can be explained by the corresponding variation in x ans the least squares line? What percentage is unexplained? ( Round your answer for r2 to four decimal places. Round your answers for the percentages to two decimal places.) r2 = explained = __%unexplained=__%c) for a neighborhood with x=45 hundred jobs, how many are predicted to be entry level jobs?(Round your…
