Would you say that homes in this country have more than 1.8 rooms per person on​ average? State your hypotheses and calculate a​ P-value. State conditions and assumptions​ clearly, and indicate whether they are likely to be true. Use a significance level of alphaαequals=0.05. Let muμ be the population mean number of rooms per person in the given country.

Determine the null and alternative hypotheses.
