An average computer mouse inspector can inspect 50 mice per hour. The 48 computer mice inspectors at a particular factory can on
Ronch [10]

Answer:  C. Yes, because -2.77 falls in the critical region .

Step-by-step explanation:

Let \mu be the population mean .

As per given , we have

H_0:\mu=50\\\\ H_a: \mu

Since the alternative hypothesis is left-tailed and population standard deviation is not given , so we need to perform a left-tailed t-test.

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

Also, it is given that ,

n= 48

\overline{x}=46

s= 10

t=\dfrac{46-50}{\dfrac{10}{\sqrt{48}}}=\dfrac{-4}{\dfrac{10}{6.93}}\\\\=\dfrac{-4}{1.443}\approx-2.77

Degree of freedom = df = n-1= 47

Using t-distribution , we have

Critical value =t_{\alpha,df}=t_{0.025,47}=2.0117

Since, the absolute t-value (|-2.77|=2.77) is greater than the critical value.

So , we reject the null hypothesis.

i.e. -2.77 falls in the critical region.

[Critical region is the region of values that associates with the rejection of the null hypothesis at a given probability level.]

Conclusion : We have sufficient evidence to support the claim that these inspectors are slower than average.

Hence, the correct answer is C. Yes, because -2.77 falls in the critical region

kiruha [24]

Answer:

Calculate the Macaulay duration of Annuity B at the time of purchase is 1.369.

Step-by-step explanation:

First, we use 0.93 to calculate the v which equals 1/(1+i).

\frac{0+1*v+2v^{2} }{1+v+v^{2} } = 0.93

After rearranging the equation, we get 1.07v^{2} + 0.07v - 0.93=0

So, v=0.9

Mac D: \frac{0+1*v+2*v^{2}+ 3*v^{2} }{1+v+v^{2}+ v^{3} }

After substituting the value of v, we get Mac D = 1.369.

WILL GIVE BRAINLIEST! In any boxplot, what percent of the data is above the 3rd quartile?
Margarita [4]
75% because a third quartile is 3/4 which is 75% which if you break each fourth down it would be 25% so then you multiply 25%x3 to get 75%

1. Find the slope of the line passing through (-3,-4) and (-6,-2).
r-ruslan [8.4K]

Answer:

slope = - \frac{2}{3}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 3, - 4) and (x₂, y₂ ) = (- 6, - 2)

m = \frac{-2+4}{-6+3} = \frac{2}{-3} = - \frac{2}{3}

elena-14-01-66 [18.8K]

Answer:

1/3

Step-by-step explanation:

Slope is always represented by m in the equation y=mx+b. Therefore, the value that is attached to the x is always the slope.
