Suppose that Y₁, Y2Yn is a random sample from a normal distribution with parameter mean
0 and variance 0, say N(0, 0). If Mr Masela and Mr Sepuru desire to use 5% level of
significance to test the null hypothesis Ho: 0 = 1 against alternative hypothesis H₁:0>1.
1) Show that the uniformly most powerful test of their hypothesis rejects Ho if
Ey ≥c where is a constant that solves the probability equation
0.05= POZY ≥ c0 = 1).
ii) What will be the value of c in part a) if n = 15.
An academic Professor conducted a research aimed at exploring the experience and
challenges faced by people who are diagnosed with dementia and their families. If the
professor perform a hypothesis test to decide whether the mean age of all people diagnosis
with initial occurrence of dementia is less than 55 years old. Based on the statement, explain,
what each of the following would mean.
i) Type I error.
iii) Type Il error.
that the results of carrying out the hypothesis test lead to non-rejection of the null
