In a clinical setting it may be prudent to take the blood pressure of pigs. Suppose that a random sample of 32 pigs yields a mean systolic blood pressure of 118 mmHg with a standard deviation from the sample of 16 mmHg.
Use the information provided to estimate the mean systolic blood pressure of all pigs at 90% confidence.
1. State the conditions required to calculate this estimate AND comment on how they were met:
2. Mechanics: Write the formula with relevant substitutions and results.
3. Interpret the results in context.
4. A vet tech claims that the average systolic blood pressure of all pigs is 110 mmHg. Is this a reasonable claim? Why or why not?
