Answer:
Step-by-step explanation:
The null hypothesis is the hypothesis that is assumed to be true. It is an expression that is the opposite of what the researcher predicts.
The alternative hypothesis is what the researcher expects or predicts. It is the statement that is believed to be true if the null hypothesis is rejected.
From the given situation,
news article says that high school students are currently spending an average of 15 hours per week doing homework online. This is the null hypothesis.
H0: µ = 15 hours
You don't think this is an accurate estimate, although you're not sure whether the real value is higher or lower. This is the alternative hypothesis.
Ha : µ ≠ 15 hours
0.85 is between 0.8 and 0.9
Answer:
2
Step-by-step explanation:
<em>"How many ways can we choose a Senator from a chosen state?"</em>
Each state has 2 Senators. So there are 2 ways we can choose a Senator from any selected state.
<em>"How many ways can we choose 3 states to be represented?"</em>
The order in which the states are selected isn't important, so the number of ways 3 states can be selected is:
₅₀C₃ = 19,600
<em>"How many ways can the 3-Senator committee be formed such that no 2 Senators are from the same state?"</em>
The number of ways a committee can be formed is:
2×2×2×19,600 = 156,800
