Answer:

Given hypothesis are

H0: A = 0.24

H1: Â ≠ 0.24

Here sample proportion  is used to express hypothesis instead of population proportion p.

The error is sample parameter  used in hypothesis [ It should be population parameter p or π )

Step-by-step explanation:

Based on the information given, the error that can be seen is that sample proportion  was used in expressing hypothesis rather than population proportion p.

From the information given, the null and alternate hypothesis is given as:

  • H0: A = 0.24
  • H1: Â ≠ 0.24

The error made was that the sample proportion  was used to express hypothesis instead of population proportion p. In this case, it should be population parameter p or π. This was the error.
