Good credit: The Fair Isaac Corporation (FICO) credit score is used by banks and other lenders to determine whether someone is a good credit risk. Scores range from 300 to 850 , with a score of 720 or more indicating that a person is a very good credit risk. An economist wants to determine whether the mean FICO score is more than the cutoff of 720 . She finds that a random sample of 90 people had a mean FICO score of 730 with a standard deviation of 91 . Can the economist conclude that the mean FICO score is greater than 720 ? Use the \( \alpha=0.10 \) level of significance and the \( P \)-value method and Excel.

There are organisms that go through meiosis but do not undergo recombination when forming haploid gametes. Which of the following statements correctly describes the gametes produced by such an organism? (Assume that these organisms are diploid, that each of the two homologous chromosomes are genetically distinct as typically found in the wild, and that these organisms have more than one chromosome.) All gametes formed during a single meiosis will be identical. This organism could potentially produce $2^n$ genetically distinct gametes, where $n$ is its haploid number of chromosomes. Due to the random assortment of homologs, each of the gametes formed during a single meiosis will be different The fusion of any two gametes produced by such an organism that does not undergo recombination during meiosis will create a cell that is genetically identical to that individual
