1. a)What is your null hypothesis regarding sepal lengths for the two species? And what is your alternate hypothesis?
b) Describe your hypotheses in terms of your test statistic: what would be the t under the null hypothesis, H₀, and what would be the statement about t under your alternate hypothesis H_a? Would you do a one- or non-(i.e., two-sided) directional test? Why?

1) What is a hypothesis, a hypothesis test, a null hypothesis and an alternative hypothesis? 2) What is a P-value, critical value and a test statistic? Provide an example of each and describe how they are used to test claims. 3) When conducting a hypothesis test, what is the difference between the P-value method and the critical-value method? 4) List and explain all the steps for performing a hypothesis test. Directions: write the finding of these questions in a short...

Hypothesis testing conceptual questions: a. Define the null and alternative hypothesis b. What are the two errors that can occur in hypothesis testing? What mathematical symbols are used to denote these errors? c. Define the P-value. How are P-values used in hypothesis testing? d. How is the significance level of a hypothesis test determined? e.

Two key concepts in hypothesis testing are the null and the alternative hypothesis. Formulating the hypothesis test in the right manner, i.e. by correctly formulating null and alternative hypothesis is the first step towards solving the problems in the right manner. How do we represent these concepts tl (i.e. what abbreviation we use to denote null and alternative hypothesis)?

1. In your own words, how is a null hypothesis, different from a research hypothesis? 2. A statistician is faced with increasing the chances that she will make a Type I error or increasing the chances that she will make a Type II error. What advice do you give to her? Why? 3. Discuss how the terms “level of significance” and “critical region” are related. 4. Why would a researcher test a one-tailed vs. a two-tailed hypothesis? 5. Why would...
