### Understanding Type I Errors in Hypothesis TestingA Type I error, also known as a "false positive," occurs in hypothesis testing when a true null hypothesis is incorrectly rejected. This means that the test suggests there is an effect or difference when, in fact, none exists. Understanding Type I errors is crucial for accurate data analysis and scientific research.Below are multiple-choice options to test your understanding of Type I errors:1. **Making a correct decision in a hypothesis test.**2. **When a correct null hypothesis is rejected in a hypothesis test.**3. **Usually not controlled for in a hypothesis test.**4. **When a correct alternative hypothesis is rejected in a hypothesis test.**5. **Both (c) and (d) are true.**### Answer Key:Option 2 is the correct definition of a Type I error.**Note:** In the image, an annotation marks the correct answer as option 2.Understanding and controlling for Type I errors is essential for ensuring the validity and reliability of your hypothesis testing results.

Suppose you have a hypothesis test which never rejects the null hypothesis, no matter the value of the test statistic. Name a potential problem with such a test. Select one: a. There can be no problem with such a hypothesis test, this is the ideal scenario. b. Using this test would lead to making an excessive number of Type I errors. c. Using this test would lead to making an excessive number of Type II errors.
Which hypothesis test would be appropriate to determine whether the new variety of orange has a significantly higher content of vitamin C than the variety that is currently the top seller? Do NOT perform a hypothesis test – simply tell me which test should be used, why you chose this test, and give the formula for the test statistic.
A scientist has read that the mean birth weight, u, of babies born at full term is 7.5 pounds. The scientist, believing that u is different from this value, plans to perform a statistical test. She selects a random sample of birth weights of babies born at full term and finds the mean of the sample to be 7.9 pounds and the standard deviation to be 1.6 pounds. Based on this information, answer the questions below.
