Ответ:
Null hypothesis Uo = 165
Alternative Hypothesis U1 > 165
Step-by-step explanation:
Null hypothesis = 55% of registered voters
In this case we sampled on 300 voters
55/100 × 300= 165voters
Null hypothesis Uo= 165
That is 165 out of 300 voters will favour legalized gambling.
Alternative Hypothesis U1 > 165
That is more than 165 out of 300 voters will favour legalized gambling.
