A colorful frog species has four color morphs. It's been hypothesized that frequency-dependent selection will stabilize the color morphs in a population to a 1:1:1:1 ratio.
You collect 160 frogs and observe the following numbers:
| red spot | 34 |
| yellow | 48 |
| blue stripe | 40 |
| pink chevron | 38 |
The question of interest is whether the frogs in this population are in a 1:1:1:1 ratio.
Step 2: State the null hypothesis.
Step 3: State the alternative hypothesis.
Step 4: What is the correct level of alpha?
Step 5: Which statistical test are you using?
Step 6: What is the value of the test statistic?
Step 6 continued: How many degrees of freedom in this test?
Step 7: What is the critical value for the test statistic?
Step 8: How does the test statistic compare to the critical value?
Step 9: Based on this comparison, do you accept or reject your null hypothesis?
Step 10: What do you conclude from this analysis?

A large survey of countries, including the United States,China, Russia, France, Turkey, Kenya, and others, indicate that most people prefer the colorblue. In fact, about 24% of the population claim blue as their favorite color (Reference: Study byJ. Bunge and A. Freeman-Gallant, Statistics Center, Cornell University). Suppose a randomsample of 56 college students were surveyed and 12 of them said that blue is their favoritecolor. Does this information imply...

A drug which is used for treating high cholesterol has potentially dangerous side effects if it is taken at an improper dosage. The drug is manufactured at two different plants, plant A and plant B. A medical researcher believes that tablet A has a smaller variance in dosage than the variance in dosage from tablet B. The sample variance of a sample of 6 dosages of tablet A is 0.016. The sample variance of a sample of 20 dosages of...

You recently obtained a job with a sports analytics firm, and your first assignment is to write a report evaluating early evidence behind predictions for the 2019-20 NBA season. You will use your knowledge of hypothesis testing to assess the predictions. 1. When conducting a hypothesis test for the population mean, you will not know the population standard deviation, so you will have to use the sample standard deviation instead. How will this affect the process? 2. The 2019-20 season...
