Final answer:

An appropriate hypothesis statement for the study would include a null hypothesis stating the average height of adult BTC students is 69.2 inches and an alternative hypothesis stating it is not equal to that value.

Step-by-step explanation:

An appropriate formal hypothesis statement for Eduardo's study to determine if the average height of adult BTC students is different than the national average would be:

Null Hypothesis (H0):

The mean height of adult BTC students is equal to 69.2 inches (the national average).

Alternative Hypothesis (H1):

The mean height of adult BTC students is not equal to 69.2 inches (the national average).

In formal notation:

  • H0: μ = 69.2 inches
  • H1: μ ≠ 69.2 inches

This hypothesis testing will involve collecting a sample of heights from adult BTC students, calculating their mean height, and using statistical methods such as a t-test or z-test to determine if there is a statistically significant difference from the national average.
