Answer:

a. H0 : U ≥ 15

   Ha : U < 15

b. Type I error is incorrectly conclude that the pain is reduced in less than 15 minutes.

c. Type II error is fail to conclude that time for pain reduction is less than 15 mints when actually its less than 15 minutes.

Explanation:

Null hypothesis is a statement that is to be tested against the alternative hypothesis and then decision is taken whether to accept or reject the null hypothesis.

Type I error is one in which we reject a true null hypothesis.

Type II error is one in which we fail to reject the null hypothesis that is actually false.

For a market to be competitive:a. each buyer and seller is small, relative to the whole market; no single decision-maker has any
kirill115 [55]

Answer: Option (A) is correct.

Explanation:

Each of the buyer and seller are small when we are relating it with the whole market. so, there will be no power in the hands of a single decision maker and if a firm wants to change their prices then it will not have any influence on the market price. In a competitive market, there are large number of buyers and sellers, thus, one buyer or seller doesn't have any impact on the market price.

Yuki888 [10]

Answer:

29,143

Explanation:

Profit target = 25% on sales

Fixed cost = $51,000

Variable cost = $9.50 per unit

Sales price per unit = $15

To achieve profit target, let the number of units sold be y

Total sales = 15y

Total variable cost = 9.5y

Profit = 0.25 × 15y

         = 3.75y

Sales - Cost = profit

15y - (51000 + 9.5y) = 3.75y

15y - 9.5y - 3.75y = 51000

1.75y = 51000

y = 51000/1.75

y = 29143

29,143 bears must be sold to meet the profit goal.

Ari, Inc. is working on its cash budget for December. The budgeted beginning cash balance is $14,000. Budgeted cash receipts tot
Andreas93 [3]

Answer:

The company needs to borrow $25000 and option B is the correct answer.

Explanation:

If the ending amount of cash for the year is less than the desired ending balance, then the company will need to borrow to maintain the desired level of cash balance.

To calculate the amount needed to be borrowed, we first compute the ending cash balance for December. The ending cash balance will be,

Closing Balance = Opening Balance + Receipts - Payments

Closing Balance - December = 14000 + 127000 - 126000

Closing Balance - December = $15000

The difference between the closing cash balance and the desired closing cash balance is the amount that the firm will need to borrow.

Amount need to be borrowed = 40000 - 15000  =  $25000
