A quality control manager has concerns about the occurrence of defects on a
component assembly used in the fabrication of an aircraft wing. The manufacturing plant
operates with three shifts, and three particular types of defects are of concern. The following
table shows the count of defects of each type across the shifts from a random sample of 300
assemblies with defects from a week of production.
Test whether the types of defects are independent of the shifts. Perform the test on the 5%
level. What is your conclusion?

- 18Five loci defined by microarrays are known to contribute to meat quality in cattle. These can be tested using microarrays. Premium meat quality occurs when eight or more of the alleles at these five loci are of the “contributing” variety. An uppercase letter indicates a contributing allele and lowercase letter indicates a noncontributing allele. One can determine the genotype of cattle with a microarray. If the following genotypes of a cow and a bull (respectively) are crossed, what is the probability the first offspring will have eight or more contributing alleles? Assume all loci are autosomal and independent.

- QDOS-C Are there more children diagnosed with Autism Spectrum Disorder (ASD) in states that have larger urban areas over states that are mostly rural? In the state of Pennsylvania, a fairly urban state, there are 245 eight year olds diagnosed with ASD out of 18,440 eight year olds evaluated. In the state of Utah, a fairly rural state, there are 45 eight year olds diagnosed with ASD out of 2,123 eight year olds evaluated ("Autism and developmental," 2008). Is there enough evidence to show that the proportion of children diagnosed with ASD in Pennsylvania is more than the proportion in Utah? Test at the 1% level. (vii) Using tables, calculator, or spreadsheet: Determine and enter p-value corresponding to test statistic. Enter value in decimal form rounded to nearest thousandth.
