A company is selling Tulip bulbs, and claim that they have equal number of white, pink, yellow, and purple bulbs, and that when customers order them, they randomly select the bulbs from those that they have. You ordered 30 bulbs and received 14 white, 6 pink, 7 yellow, and 3 purple bulbs. Is there evidence that the bulbs you received were not randomly selected from a population with equal proportion of white, pink, yellow, and purple bulbs? Test at 5% level of significance.
The appropriate null hypothesis for the test is _________.
If the null hypothesis is true, what are the expected counts?
The value of the test statistic is ______.
The degrees of freedom of the test is ______.
The p-value of the test is ______.
The conclusion in the context of the problem is ______.

Stats Hw- Please Help 3. A company that manufactures compact fluorescent light bulbs (CFL) claims that they will operate for a mean of 10,000 hours with a level of significance equal to 0.05. An engineer from the company performs a test to validate this claim. The hypotheses are: Null hypothesis: μ = 10,000 hours Alternate hypothesis: μ ≠ 10,000 hours The engineer does accelerated lifetime testing on 50 of these bulbs and finds that the mean lifetime is 9875 hours...

A genetic experiment involving peas yielded one sample of offspring consisting of 434 green peas and 137 yellow peas. Use a 0.01 significance level to test the claim that under the same circumstances, 25% of offspring peas will be yellow. Identify the null hypothesis, alternative hypothesis, test statistic P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method and the normal distribution as an approximation to the binomial distribution. What are the...

A coworker claims that Skittles candy contains equal quantities of each color (purple, green, orange, yellow, and red). In other words, 1/5 of all Skittles are purple, 1/5 of all Skittles are green, etc. You, an avid consumer of Skittles, disagree with her claim. Test your coworker's claim at the α=0.01α=0.01 level of significance, using the data shown below from a random sample of 200 Skittles. Which would be correct hypotheses for this test? H0:H0: Red Skittles are cherry flavored;...
