Solution Steps

Step 1: Identify the Given Values

We are given the following values:

  • Mean monthly rent, μ=970\mu = 970
  • Standard deviation, σ=204\sigma = 204
  • John's rent, X=1390X = 1390
Step 2: Calculate the Z-Score

The formula for calculating the standardized zz-score is:

z=X−μσ z = \frac{X - \mu}{\sigma}

Substituting the given values:

z=1390−970204=420204≈2.0588 z = \frac{1390 - 970}{204} = \frac{420}{204} \approx 2.0588

Step 3: Round the Z-Score

Round the zz-score to three decimal places:

z≈2.059 z \approx 2.059

Final Answer

z≈2.059\boxed{z \approx 2.059}

1. Make a well-labeled diagram of your actual gel results below. The wells are indicated by the boxes. Discussion 1. The Introduction mentioned that there are three possible results when testing a given DNA sample. Each possible result is run in its own lane of an agarose gel. Describe and draw what these three lanes would look like. The three possible results represent different genotypes for a particular DNA sequence. Homozygous present indicates two copies of the allele, homozygous absent indicates no copies, and heterozygous indicates one copy of the allele. The gel electrophoresis separates the DNA fragments by size. The presence or absence of the allele affects the size of the DNA fragment and thus its migration through the gel, resulting in distinct band patterns for each genotype. It is expected that different cell types from the same patient would show the same banding pattern reflecting the same genotype. 2. Based on the expected results for the gel (NOT the actual results you sketched above), what can you conclude about the genotype of the patient in her different cell types? Explain your answer.
