Written as a one-page management memo, this GB513 Unit 6 hypothesis test example reports a one-sample t test on branch wait times and recommends extending the pilot. Searches like "gb 513 unit 6 assignment example", "gb513 unit 6 sample" and "gb513 unit 6 example" land here.
What a finished GB513 Unit 6 hypothesis test memo looks like
A standard memo header addresses the bank's retail operations vice president, with a subject line naming the vendor claim. The opening paragraph gives the conclusion: the pilot data do not provide sufficient evidence that average wait fell below five minutes at the 0.05 level. A compact box follows with the hypotheses in symbols and in words, the significance level, the sample mean of 4.6 minutes, the standard deviation, the t statistic and the p-value. Two short paragraphs explain the result in banking terms and what a type II error would mean here, a real improvement missed because 40 visits are too few. The memo ends with a recommendation to extend the pilot by a month and a sample size target. Excel output appears in an attachment.
How a GB513 Unit 6 example is structured
The memo puts the answer before the evidence because its reader is deciding a contract, not checking arithmetic. Hypotheses are stated before any number appears, with the claim placed in the alternative, since the vendor must prove the improvement and the status quo is the null. The direction of the test follows from that wording and is stated once. The statistics box keeps the mechanics compact and in the order a reader checks them. Interpretation follows in two moves: the statistical decision, failing to reject the null, and then its scenario sentence, which says the pilot has not shown the promised reduction. The type II paragraph explains why failing to reject is not proof the software does nothing. The recommendation is sized to the evidence: more data, not cancellation, with the sample size that would detect a half-minute difference.
Conclusion in the first lines
Two sentences answer the vice president's question and name the significance level. The rest of the memo supports them, which is the format this unit's graders usually expect.
Claim placed in the alternative
H0 states that mean wait is five minutes or more; H1 states it is below five. A plain-language line under each symbol says what it would mean for the branches, so a reader without statistics training follows the setup.
The statistics box
Sample size, mean, standard deviation, t statistic, degrees of freedom and one-tailed p-value, each labeled, with the Excel function noted. Nothing in the box is repeated in the paragraphs.
What failing to reject means
A short paragraph separates absence of evidence from evidence of absence. The sample mean did fall, but not by enough, given the variability, to rule out chance at the chosen level.
More data, not a verdict
Extending the pilot is recommended over both rollout and cancellation, with a target of roughly 120 timed visits and a decision date. The memo notes that the cost of waiting is small relative to the contract.
Where marks go in GB513 Unit 6
Hypothesis setup is where this memo most often loses credit. Placing the vendor's claim in the null, or writing hypotheses about the sample mean instead of the population mean, is treated as wrong in most sections regardless of what follows. A two-tailed p-value used for a one-tailed question is the most frequent computation error. The next deduction comes when the statistical verdict is left in the language of the test, with nothing translating it into the bank's terms. Concluding that the null is proven true loses interpretation points. Memo conventions carry weight as well: a missing header, a conclusion buried in the last paragraph, or an essay-style introduction reads as the wrong genre. Recommendations that ignore the strength of the evidence, dropping the vendor on one inconclusive sample, draw comments about managerial judgment.

GB513 Unit 6 questions, answered
Which hypothesis should contain the claim being tested?
The claim that requires evidence belongs in the alternative. When a vendor, a manager or a campaign asserts an improvement, the null keeps the status quo and the data must overturn it. Some prompts phrase the claim as an equality, and then it sits in the null. A finished memo explains its choice in one line, which prevents most setup deductions.
Is a p-value of 0.09 close enough to call the result significant?
Not at a 0.05 level set in advance. Changing the level after seeing the result undermines the test, and instructors spot it. What a memo can do is report the p-value honestly, say the evidence is suggestive but insufficient, and recommend gathering more data. That reads as sound judgment rather than a failed test.
Does the memo need an APA title page?
Usually not. A memo format replaces the title page with its header block, and many sections accept references at the end in APA style if sources are cited. Check the rubric, since a few instructors want the memo embedded in a formal paper. The example follows the memo convention because its prompt frames a manager as the reader.
