the null hypothesis

10. A coin-operated drink machine was designed to discharge a mean of 6 ounces of coffee per cup. Suppose that we want to carry out a hypothesis test to see if the true mean discharge differs from 6 . State the null hypothesis H0 and the alternative hypothesis H1 that we would use for this test.H0 :  H1 :

the true mean of all scores.

6. The standard deviation of test scores on a certain achievement test is 11.5. A random sample of 90 scores on this test had a mean of 75.3. Based on this sample, find a 90% confidence interval for the true mean of all scores. Then give its lower limit and upper limit.Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.)Lower limit:Upper limit:

national and cultural identity

Music and dance

Respond to the following in a minimum of 175 words:

Music and dance are similar because both are able to communicate ideas and emotions without the use of words. In the absence of a vocal part, musicians create sounds that evoke certain emotions. Composers and performers do this through different elements of music like melody, harmony, and rhythm. Dancers can also communicate emotions, ideas, or even a story through their movements, and these movements are often tied to musical elements like rhythm.

Imagine that you are composing a ballet. Pick an emotion that you want to show the audience. Describe how you would use certain elements of music to create the sounds of that emotion. How would you choreograph the dancers to align with your musical ideas?
