Tanda is planning to DJ a remote dance party to cheer up the neighborhood, so she surveys a random sample of Avocado Park residents about what type of dance party they are in the mood for. The results can be found in ______.
a. The first thing Tanda needs to establish is whether any of the themes are more popular than any of the others. What would be her null hypothesis in this case?
b. What would be a suitable alternative hypothesis to go along with the null hypothesis from part a?
c. Are the necessary conditions for this type of hypothesis test met? What must you assume?
d. Compute the P-Value based on your hypotheses from parts a and b, under the assumptions you stated in part c.
e. Using a significance level of 0.10 and your P-Value from part d, should the null hypothesis be rejected?
f. State a conclusion summarizing your results from parts a-e.
