In 2010, the average duration of long-distance telephone calls originating in one town was 9.4 minutes. A long-distance telephon
Zepler [3.9K]

<u>Answer</u>: No, we do not have sufficient evidence to conclude that the mean call duration, µ, is different from the 2010 mean of 9.4 minutes.

Step-by-step explanation:

As per given , we have

H_0: \mu=9.4\\\\H_a:\mu\neq9.4, since H_0 is two-tailed so , the test is a two tail test.

Since population standard deviation is unknown, so we use t-test.

Critical value (two-tailed) for significance level of 0.01= t_{n-1,\alpha/2}=t_{49, 0.005}\pm2.609228

For n =50 , \overline{x}=8.6 and s= 4.8

Test statistic : t=\dfrac{\overline{x}-\mu}{\dfrac{s}{\sqrt{n}}}

t=\dfrac{8.6-9.4}{\dfrac{4.8}{\sqrt{50}}}\approx-1.18

Since test statistic value (-1.18) lies in critical interval (-2.609228, 2.609228), it means the null hypothesis is failed to reject.

We do not have sufficient evidence to conclude that the mean call duration, µ, is different from the 2010 mean of 9.4 minutes.

If m∠c=11x+85/3 and x=13 then what type of angle is c please help me with this
GuDViN [60]

Answer:

Acute angle

Step-by-step explanation:

Given that m<C = \frac{11x + 85}{3}, to find out the type of angle angle C is, evaluate the expression given by substituting x = 13, in the expression.

m<C = \frac{11x + 85}{3}

m<C = \frac{11(13) + 85}{3}

m<C = \frac{228}{3}

m<C = 76°

Acute angles are less than 90°.

m<C is less than 90°, therefore it is an acute angle.

Can you help with this to?
love history [14]

Answer:

total change in time when you used 5 clues is 10.

Step-by-step explanation:

if you have 3 free clues, then 5-3 =2

That means you used 2 additional clues. 2 clues means 5*2 min reduced which is 10 mins reduced. The total time you have is x and the total time left is x-10 after you used the two clues.

Does this help?

Simplify the expression. 5/8*(18*3+(-22))+(-45)
lubasha [3.4K]
Using PEMDAS
(Parenthesis)(Exponents)(Multiplication/Division)(Addition/Subtration)
So:
\frac{5}{8} * ((54-22)-45) =  \frac{5}{8}*(32-45) =  \frac{5}{8}(-13)
=  \frac{-65}{8}= -8.125
