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.

Read the fine print, if it says “after signing, this contract is final.” Then Otto is screwed, because he must pay the $50,000

Barbara Smith is an employee of Allied Manufacturing Company. She has an 8-hr workday and each day is paid $0.60 for each unit p
MariettaO [177]

Answer:

$309

Explanation:

The computation of the gross earning for the week is as follows:

Given that

Payment of $7.15 × 8 = $57.2  or payment of  each unit produced whichever is greater

On monday

= 90 units × $0.60

=  $54

But the greater is $57.2

On tuesday

= 114 units × $0.60

=  $68.4

On Wednesday

= 82 units × $0.60

= $49.20

But the greater is $57.2

On thursday

= 112 units × $0.60

= $67.20

On friday

= 98 units × $0.60

= $58.80

Now the earnings for the last week is

= $57.20 + $68.4 + $57.20 + $67.20 + $58.80

= $308.80

= $309

jonny [76]

Answer:

400,000

Explanation:

7% of what number = 28,000

(0.07)(X) = 28,000

X = 400,000

(which is less than 700,000. But that makes sense because not everyone living in Michael's city is necessarily part of the labor force. Some could be kids in school, others grandparents who have retired, others people who stay at home and don't work.)

What affects the egg coagulation in custards and creams!

What affects the egg coagulation in custards and creams!
Answer: Sugar is also important to custard as the addition of it in a recipe results in a softer custard. Sugar also increases the coagulation temperature and time. Don't dump the sugar directly onto the eggs and let it sit; this causes the yolks to "burn" into hard little lumps that detract from your creamy custard.
