Mary is the manager of a new clothing shop. The shop located in a new shopping mall and Mary wants to estimate the average daily
sergeinik [125]

<u>Explanation:</u>

a) First, note that the Type I error refers to a situation where the null hypothesis is rejected when it is actually true. Hence, her null hypothesis would be H0: mean daily demand of her clothes in this region should be greater than or equal to 100.

The implication of Type I error in this case is that Mary <u>rejects</u> that the mean daily demand of her clothes in this region is greater than or equal to 100 when it is actually true.

b) While, the Type II error, in this case, is a situation where Mary accepts the null hypothesis when it is actually false. That is, Mary <u>accepts</u> that the mean daily demand of her clothes in this region is greater than or equal to 100 when it is actually false.

c) The Type I error would be important to Mary because it shows that she'll be having a greater demand (which = more sales) for her products despite erroneously thinking otherwise.

in one year Orlando receive 62.51 inches of rain in September the city received 25% of that rainfall about how much rain did Orl
Angelina_Jolie [31]

Answer: 15.6275 inches of rain in September in Orlando.

How-To: percentages can be changed into decimals, by dividing 100. 25%/100=.25
The decimal .25=25%
So take 62.51 and multiply it by .25 and you get 15.6275

Write the equation for the perpendicular bisector of the given line segment.
Anon25 [30]

Answer:

y=\frac{1}{3}x+\frac{5}{3}

Step-by-step explanation:

Let

A(-5,5),B(-2,-4) ----> the given segment

step 1

Find the slope AB

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the given values

m=\frac{-4-5}{-2+5}

m=\frac{-9}{3}

m=-3

step 2

we know that      

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of the slopes is equal to -1)

so

the slope of the perpendicular bisector is equal to

m_1*m_2=-1

we have

m_1=-3

substitute

(-3)*m_2=-1

m_2=\frac{1}{3}

step 3

Find the midpoint segment AB

A(-5,5),B(-2,-4)

The formula to calculate the midpoint between two points is equal to

M(\frac{x1+x2}{2} ,\frac{y1+y2}{2})

substitute the values

M(\frac{-5-2}{2} ,\frac{5-4}{2})

M(-\frac{7}{2} ,\frac{1}{2})

step 4

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=\frac{1}{3}

M(-\frac{7}{2} ,\frac{1}{2})

substitute

y-\frac{1}{2}=\frac{1}{3}(x+\frac{7}{2})

step 5

Convert to slope intercept form

y=mx+b

isolate the variable y

y-\frac{1}{2}=\frac{1}{3}x+\frac{7}{6}

y=\frac{1}{3}x+\frac{7}{6}+\frac{1}{2}

y=\frac{1}{3}x+\frac{10}{6}

simplify

y=\frac{1}{3}x+\frac{5}{3}

see the attached figure to better understand the problem
