You have been hired to test whether the demand for a product that your client produces varies between two demographic markets – the Urban and Rural markets.
As such, in each market, you run a short survey that gauges customers demand for your product and assigns them to one of three categories – (i) High (ii) Medium or (iii) Low.
You survey 70 people in the “Urban” market and find that their demand falls into the following “buckets”
High 32
Medium 20
Low 18
You survey 30 people in the “Rural” market time. Their demand for the product its reflected below.
High 8
Medium 10
Low 12
The Null hypothesis that you are asked to test is that "the demand for the product is INDEPENDENT of the whether the market is Urban or Rural.”
Assuming that you can tolerate no more than a 5% probability of a Type I error ("p" no larger than 0.05), what is the critical value for the Chi-Square test of the above hypothesis?

12) You want to test your hypothesis that the purple and wrinkled genes in corn are linked. You cross a corn plant that breeds true for the dominant traits of purple, wrinkled kernels (PP ss) with a plant breeds true for yellow, smooth kernels (pp SS). You then cross the offspring with a yellow, wrinkled tester and obtain offspring with the phenotypes listed below. In the blank after each phenotype, indicate with an R or a P whether that type...

Conduct the hypothesis test and provide the test statistic and the critical value, and state the conclusion. A person randomly selected 100 checks and recorded the cents portions of those checks. The table below lists those cents portions categorized according to the ated values Use a 0.10 significance level to test the claim that the four categories are equally likely. The person expected that many checks for whole dollar amounts would result in...

13. Multiple choice: Select the best answer. (4pts) In storm crabs, red eyes (ry+) is dominant to blue eyes (ry), and spines (spt) is dominant to no spines (sp). You performed a test cross with a crab heterozygous for these characteristics. Which of the following chi-squared values would indicate significant linkage between these two loci? You may consult the table below. a. 0.025 b. 0.121 c. 0.455 d. 1.887 e. 4.432 f. None of the above are significant. f None...

In a flowering plant, red flowers are dominant over white flowers, and short plants are dominant over tall plants. A short plant with red flowers was self-fertilized and the phenotypes for the resulting progeny recorded (see below). Based on the observed numbers, you propose the hypothesis that this dihybrid cross follows a 9:3:3:1 phenotypic ratio, whereby Mendel's laws apply. Based on this hypothesis, you calculated the expected number of progeny for each phenotype (see below). Phenotype Observed Number of Plants...
