You measure 41 textbooks' weights, and find they have a mean weight of 30 ounces. Assume the population standard deviation is 12.3 ounces. Based on this, construct a 93% confidence interval for the true population mean textbook weight. Round z-values to 2 decimal places; round t-values to 3 decimal places. Round final answers to 2 decimal places.
Answers
Answer:
The 93% confidence interval is [tex] 26.52 < \mu < 33.48 [/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 41
The mean is [tex]\= x = 30[/tex]
The standard deviation is [tex]\sigma = 12.3[/tex]
From the question we are told the confidence level is 93% , hence the level of significance is
[tex]\alpha = (100 - 93 ) \%[/tex]
=> [tex]\alpha = 0.07[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.81[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]E = 1.812 * \frac{12.3}{\sqrt{41} }[/tex]
=> [tex]E = 3.48 [/tex]
Generally 93% confidence interval is mathematically represented as
[tex]\= x -E < \mu < \=x +E[/tex]
=> [tex] 30 -3.48 < \mu < 30 + 3.48 [/tex]
=> [tex] 26.52 < \mu < 33.48 [/tex]

C: 1920 gallon
D: 1120 gallons
Answers
Answer:
19/20
Step-by-step explanation:
you spelled them wrong A is 1/5 B is 3/4 C is 19/20 D is 11/20 but C is the right answer
The leftover gallon of paint she has now is C: 19/20 gallon
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, Aisha had 2 gallons of paint.
She used 4 /5 of the first gallon and 1/4 of the second gallon.
∴ The amount of leftover paint is 2 - (4/5 + 1/4).
= 2 - (16 + 5)/20.
= 2 - 21/20.
= (40 - 21)/20.
= 19/20.

65,000 (Cost) – 5,000 (Salvage Value) ÷ 60 (5 years X 12 months per year) = 1,000 in depreciation per month.
a) Accumulated depreciation from 1/1/12 to 1/1/15 is 36,000 (12 months for 2012, 2013, & 2014).
Assuming that sale was a Cash sale, the journal entry would look like this:
1/1/15
Cash (DR) 31,000
Accumulated Depreciation (DR) 36,000
Equipment (CR) 65,000
Gain on Sale of Equipment (CR) 2,000
b) Accumulated depreciation from 1/1/12 to 5/1/15 is 40,000 (12 months for 2012, 2013, 2014, & 4 months for 2015).
Assuming that sale was a Cash sale, the journal entry would look like this:

Round 2.500 g to the nearest whole gram
Answers
Answer:
Step-by-step explanation:
3 grams.
Answer:
3 grams
Step-by-step explanation:
Whole numbers do not include any decimals. They include numbers such as 1, 2, 3, 4, 5...
2.500 g is equal to 2 and a half grams, which we know is between 2 and 3 grams. This means that the nearest whole gram has to be 2 or 3.
When rounding, look at the digit to the right of the digit being rounded, and if it is 5 or more, round up. If it is 4 or less keep the digit same.
Here, 5 is the digit to the right of 2, so we round up to 3 grams.

Answers
Step-by-step explanation:

convert mixed numbers into improper fractions (whole number × denominator + numerator)
7 × 5 + 1 = 36
49 × 5 + 7 = 252
36/5 × 252/5 = 49
All fractions must have a common denominator
49 × 5 = 245
36/5 × 252/5 = 245/5
Add numerators

How much money will Jackson pay in interest for one month?
А

B
$212.45
С
$254.93
D
$2,124.45
Answers
Given :
Jackson wants to buy a new car and needs a car loan.
The cost of the car is $28,326. The car loan interest rate is 0.9% per year.
To Find :
How much money will Jackson pay in interest for one month.
Solution :
Interest on the loan is given by :
[tex]I=28326\times 0.009\\\\I=\$254.934[/tex]
Amount Jackson will pay in interest for each month is :
[tex]A = \dfrac{254.934}{12}\\\\A = \$21.24[/tex]
Therefore, Jackson will pay $21.24 dollar interest per month.
Hence, this is the required solution.
