Imagine that you have a random sample of the ages of teachers at the local school. Which of the following hypotheses answer the following question:
Does your sample show that the true mean of all teachers is over 30 years old?
H0: μ = 30 years vs. H1: μ ≠ 30 years.
H0: μ ≤ 30 years vs. H1: μ > 30 years.
H0: μ ≥ 30 years vs. H1: μ < 30 years.
Homework Answers
Solution:
Our hypothesis statement is that does your sample show that true mean of all teachers is over 30 years old?
Null hypothesis H0: mean <=30 years
Alternate hypothesis H1: mean >30 years
So it's answer is B.

The random sample data analysis showed that the mean salary of 40 elementary school teachers in study showed $28,500. Is the sample data within or out of the 95% CI the reference information (a mean of $27,000 and a standard deviation of $2,000)? Show me the process how to prove true or false on this statement (use 95% CI).

An appliance manufacturer claims to have developed a compact microwave oven that consumes a mean of no more than 250 W. From previous studies, it is believed that power consumption for microwave ovens is normally distributed with a population standard deviation of 15 W. A consumer group has decided to try to discover if the claim appears true. They take a sample of 20 microwave ovens and find that they consume a mean of 257.3 W. For this problem, the...

P-value is the probability, computed assuming H0 is true, that the test statistic would take a value as extreme or more extreme than that actually observed. Given the sample at hand, it is the smallest level of significance at which H0 would be rejected. It depends on the sample (hypotheses as well) and is hence also a test statistic. Generate 50 samples of size n=10 from a normal distribution with mean μ=1 and variance σ2=4. For each sample, use the...

Listed below are ages of actresses and actors at the time that they won an award for the categories of Best Actress and Best Actor. Use the sample data to test for a difference between the ages of actresses and actors when they win the award. Use a 0.01 significance level. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Actress's age 17 26 24 51 30...
