Recently, six single-family homes in San Luis Obispo County in California sold at the following prices (in $1,000s): 560, 468, 6

solmaris [256]

The interval for mean sale price is $582

According to statement

The given rates are 560, 468, 685, 534, 658, 593

Now,

Sample mean = X / n

Put the values in it and then

(560+ 468+ 685+ 534+ 658+ 593) / 6 = 582.1667

and use this formula S = sqrt [ X2 - n 2 / (n-1) ]

and put the values in these and

S = sqrt [ X2 - n 2 / (n-1) ] = 95.97179

So, The interval for mean sale price is $582

Answer:

When y=7,9 the answer is yes when it = -10,-8 the answer is no.

Step-by-step explanation:

Simple substitution gets us the resulting values. for y=7 we get $15\geq 15$ which is true. For y=9 we get $19\geq 15$ which is also true. For the other values we get a negative number which is not a solution.

To determine whether they need to hire extra help for the holiday season, the managers of a railroad company want to estimate ho

nadezda [96]

Answer:

Step-by-step explanation:

Data provided in the question:

Standard error = 1.5 minutes ( ∵ number are repetitive 1.51.5 )

Standard deviation = 9 minutes ( ∵ number are repetitive 99 )

Now,

Standard error = ( Standard deviation ) ÷ √n

Here,

n is the sample size

Therefore,

on substituting the respective values, we get

1.5 = 9 ÷ √n

√n = 9 ÷ 1.5

√n = 6

n = 6² = 36
