2) SLT Mobitel would like to test the hypothesis that the average revenue per retail user forEtisalat's customers equals $50. A random sample of thirty two Etisalat's customers provided anaverage revenue of $54.70. The population standard deviation for the revenue per retail user isbelieved to be $11.00. SLT Mobitel would like to set an alpha level of 0.05. Test this hypothesisusing the critical value approach.

Conclusion: Since the calculated z-value falls in the rejection region, we reject the null…

A sample of 19 account balances of a credit company showed a mean customer balance of $4,350, but the marketing manager claimed that the mean balance for the population was $4,225. The marketing manager did NOT have the population standard deviation, but the sample standard deviation was found to be $300. Use the p-value approach to conduct a full hypothesis test (all steps) that can be used to determine whether the mean of all account balances is significantly different from $4,225. Let α = .05. To help you go through the steps of hypothesis testing, follow these prompts: The null hypothesis is The alternative hypothesis is I will use a (choose 1: t / z) in my formula because I have calculated the value of t (or z) to be I have used t (or z) to get the value of p (most likely from a chart or computer printout). My p value is Alpha, which is given in the problem, is When I compared p to alpha, p is (choose 1: greater than/less than) alpha. Because of this, I know I should…
The mean number of English courses taken in a two-year time period by male and female college students is believed to be about the same. An experiment is conducted and data are collected from 24 males and 26 females. The males took an average of 4.2 English courses with a standard deviation of 1.1. The females took an average of 3.9 English courses with a standard deviation of 0.7. Conduct a hypothesis test at the 4% level of significance to determine whether the means are statistically the same. Step 1: State the null and alternative hypotheses. Ho: H1 = V H.: H1 – µ2 # v test.) (So we will be performing a two-tailed
A sample of 22 account balances of a credit company showed a mean customer balance of $4,300, but the marketing manager claimed that the mean balance for the population was $4450. The marketing manager did NOT have the population standard deviation, but the sample standard deviation was found to be $400. Use the p-value approach to conduct a full hypothesis test(all steps) that can be used to determine whether the mean of all account balances is significantly different from $4440. Let α = .05.
A sample of 27 account balances of credit company showed a mean of customer balance of 6,000, but the marketing manager claimed that the mean balance for the population was 5,558. The marketing manager did NOT have the population standard deviation, but the sample standard deviation was found to be 320. Use the p-value approach to conduct a full hypothesis test (all steps) that can be used to determine whether the mean of all account balances is significantly different from 5,558. Let a=.10
