Suppose the mean age of the population in a particular country is 53 years ( μ = 53 years) with σ = 5.5. An SRS of 100 people revealed a mean x ̅of 54.85 years. Use a two-sided test to determine if the sample mean is significantly higher than expected. α = .05

Show all hypothesis testing steps.

a)Hypothesis

b)Test Statistic

c)P-value

The mean age of the patrons of a particular nightclub has historically been 35 years. The proprietor of the nightclub wishes to find out if there is evidence that the mean age of his patrons has increased. Let μ be the mean age of the patrons of the nightclub. Step 1: State the null and alternative hypotheses. Step 2: A random sample of 41 recent evenings is selected. The average age of the patrons in the sample is 36.4 years...

The mean age when smokers first start is 13 years old with a population standard deviation of 1.8 years. A researcher thinks that smoking age has significantly changed since the invention of ENDS—electronic nicotine delivery systems. A survey of smokers of this generation was done to see if the mean age has changed. The sample of 34 smokers found that their mean starting age was 12.2 years old. Do the data support the claim at the 10% significance level? What...

A researcher suspected that age is related to depression. It is known that the general population average μ=40 on a standard depression test. The researcher obtained a sample of individuals who are more than 75 years old. The depression score of this sample are as follows: 48, 38, 42, 48, 39, 47, 41, 42, 42. On the basis of this sample, is depression for elderly people significantly different from depression in the general population at α=0.05 level? 1) State the...

Test the claim about the population mean μ at the level of significance α. Assume the population is normally distributed. Write out null and alternative hypotheses, your critical z-score and your z-test statistic. Decide whether you would reject or fail to reject your null hypothesis. Claim: μ > 28; α = 0.05, σ = 1.2 Sample statistics: x̅ = 28.3, n = 50 H0: Ha: Critical z-score: Z test statistic: Decision:

n = 36 H0: μ ≤ 20 = 24.6 Ha: μ > 20 σ = 12 1 Thirty six GGC students were sampled to determine their average age. The GGC website indicates that the average age of students was 20 years old, and you decided to conduct an upper tail test because you think the average age is higher. You collected the above information. What is the p-value of your hypothesis test. Question options: 0.5107 0.0214 0.0107 2.1 2 n...

According to my records, the population of all past assignment grades have a mean (μ) of 42 points and standard deviation (σ) of 5 points. The new class of 81 students had a mean grade (M) of 43 points. I conducted a hypothesis test to see if the new class would perform significantly differently from the population of past students. I was interested in any type of “difference,” whether it’s an improvement or a decrease in assignment grade. The significance...
