Jan Holliday Dance Studios is a chain of 45 wholly owned dance studios that offer private lessons in ballroom dancing. The studi
os are located in various cities throughout the southern and southeastern states. Holliday offers a set of 12 private lessons; students may pay for the lessons one at a time, but each student is required to enroll for at least a 12-lesson plan. The 20-, 40-, and 100-lesson plans offer savings. Each dance instructor is paid a small salary plus a commission based on the number of dance lessons provided. Required:2. Indicate whether the cost should be classified as (a) direct, (b) indirect, (c) variable, and (d) fixed with respect to the following list for the cost objects.

Answer:
If the Studio is the cost object, then all the costs that can be attributed to the studio itself will be direct and that includes all the costs except the <em>Planning and development materials sent from the home office, </em>because that comes from the home office not the studio in question.
As per the question, all the costs are also variable because there are different payment plans and the offers by the studio as well as materials needed are dependent on the number of students they have. Advertisements are a set price however and do not depend on the number of students and so are fixed .
If the Lessons were the cost objects, everything that cannot be linked directly to the lessons is an indirect cost. This includes all the costs excerpt the dancing instructors' salary as this is linked directly to the number of lessons they offer.
All costs will also be fixed because they are independent of the lessons offered and so are set amounts. The dancing instructors' salary is also fixed as the rates do not change in relation to lesson prices.

Answer:
The mean withdraw has increased during weekend.
Explanation:
Assume that the withdraw amounts are normal distributed. To test whether the mean withdrawal has increased during weekends, we take a z-test. The z-test is possible because the observed sample (weekend transactions) is greater than 30.
The null hypothesis () is when the mean withdrawal is greater than 550. The alternative hypothesis (
) is when the mean withdrawal is equal to 550 or smaller. At an alpha of 0.05% is selected with a two-tailed test, , there is 0.025% of the samples in each tail, and the alpha has a critical value of 1.96 or -1.96. If the z-value is greater than 1.96 or less than -1.96, the null hypothesis is rejected.
z-value = (600-550) / 70 / 36^(1/2) = 0.1190
At α=0.05, the z-value < 1.96 and > -1.96, the null hypothesis is not rejected. Therefore, the mean withdraw has increased during weekend.
