Test Hypotheses about a Population Mean with Known Using the Classical Approach
-A local judge claims that the mean prison time for car thieves is less than the required 4 years. A sample of 80 convicted car thieves was randomly selected, and the mean length of prison time was found to be 3 years and 6 months, with a standard deviation of 1 year and 3 months. At $\alpha = 0.05$ , test the judge's claim.

Definitions:

Chromosomes

Thread-like structures located inside the nucleus of animal and plant cells, made of protein and a single molecule of DNA, carrying genetic information in the form of genes.

Introns

Non-coding sections of DNA within a gene that are removed during mRNA processing before protein synthesis.

Exons

Sections of a gene that are expressed in the coding of a protein, interspersed with introns, which are spliced out before translation.

mRNA Transport

The process of moving messenger RNA (mRNA) molecules from the nucleus to the cytoplasm in eukaryotic cells, where they direct protein synthesis.
