A business journal investigation of the performance and timing of corporate acquisitions discovered that in a random sample of 2
weeeeeb [17]

Answer:

z = 1.960

Step-by-step explanation:

The sample proportion is:

p = 715 / 2684 = 0.2664

The standard error is:

σ = √(pq/n)

σ = √(0.266 × 0.734 / 2684)

σ = 0.0085

For α = 0.05, the confidence level is 95%.  The z-statistic at 95% confidence is 1.960.

The margin of error is 1.960 × 0.0085 = 0.0167.

The confidence interval is 0.2664 ± 0.0167 = (0.2497, 0.2831).

The upper limit is 28.3%, so the journal can conclude with 95% confidence that the true percentage is less than 29%.

A movie rental store rents DVDs for $3.50 each .How much will the store make after it rents 22 DVDs
frez [133]
Hey there! 

To solve this question simply multiply 3.50 by 22. 
Since 3.50 is the cost for 1 DVD, 22 DVD's will cost 77 dollars.

3.50 x 22 = 77

So, the store makes 77 dollars after renting 22 DVDs

The standard diameter of a golf ball is 42. 67 mm. A golf ball factory does quality control on the golf balls it manufactures. G
Mashutka [201]

Discrepancy is the difference of a the value from the uniform distribution. The function for the given situation can be given as,

f(x)=|x|-42.67

Hence the option 2 is the correct option.

Given information-

The standard diameter of the golf ball is 42.67 mm.

The discrepancy in the diameter is 0.004 mm.

<h3>What is discrepancy?</h3>

Discrepancy is the difference of a the value from the uniform distribution.

Suppose the discrepancy is x mm.

If the discrepancy in diameter is more than 0. 004 mm, the production is stopped.

As the discrepancy of 0.004 mm or more is stopped the production, we have to subtract the diameter to the discrepancy .

Thus the function for the situation can be given as,

f(x)=-42.67+|x|

Rearrange for the x,

f(x)=|x|-42.67

Thus the function for the given situation can be given as,f(x)=|x|-42.67

Hence the option 2 is the correct option.
