Answer:
Yes, we reject the auto maker's claim.
Step-by-step explanation:
H0 : μ ≥ 20
H1 : μ < 20
Sample mean, xbar = 18 ;
Sample size, n = 36
Standard deviation, s = 5
At α = 0.01
The test statistic :
(xbar - μ) ÷ s /sqrt(n)
(18 - 20) ÷ 5/sqrt(36)
-2 /0.8333333
= - 2.4
Pvalue from test statistic : Pvalue = 0.00819
Pvalue < α
0.00819 < 0.01
Hence, we reject the Null
Answer:
1. 2.11 X10^8
2. B. 1.95 X 10^-2
Step-by-step explanation: Problem 1
is equal to 211000000 which has 8 numbers after 2. So the 10 would be to the 8th power for 2.11.
Problem 2 is equal to 0.0195.
To get it to 1.95 you’re only moving the decimal 2 places, so it’s 10 X -2.
Answer:
<h3>p = 131.25</h3>
Step-by-step explanation:
The variation p varies directly with T is written as
p = kT
where k is the constant of proportionality
To find p when T =500 we must first find the formula for the variation
That's
when p = 105 and T = 400
105 = 400k
Divide both sides by 400
<h3>
</h3>
So the formula for the variation is
<h2>
</h2>
when
T = 500
Substitute it into the above formula
That's
Simplify
The final answer is
<h3>p = 131.25</h3>

Answer:
The 3 digit number 642 when multiplied 97 gives the greater product.
Step-by-step explanation:
The greatest product will result by multiplying the smaller 3 digit number with the greater two digit number.
The greater three digit number will be 976 and smaller 2 digit number would be 42
Multiplying
976*42 = 40992 ( descending order number)
679 *24= 16,296 ( ascending order number)
If we take the 2 digit number as 97 and 3digit number 642
Then multiplying
642* 97= 62,274 ( descending order number)
246 * 79=19434 ( ascending order number)
The 3 digit number 642 when multiplied 97 gives the greater product.
