A sample of 173 students using Method 1 produces a testing average of 88. A sample of 127 students using Method 2 produces a tes
Lerok [7]

Answer:

43 < μ₁ - μ₂  < 49

Step-by-step explanation:

Sample 1:

Mean      x₁    =  88

Sample size    n₁  = 173

Sample standard deviation    s₁  =  12,22

Sample 2:

Mean      x₂    =  53,5

Sample size    n₂  = 127

Sample standard deviation    s₂  =  13,59

CI   95 %        α  =  5%    α = 0,05    α/2  = 0,025

We need to find:

(  x₁  -  x₂  ) - tα/2,v *√ (s₁²/n₁ ) + (s₂²/n₂) < μ₁ - μ₂  < (  x₁  -  x₂  ) + tα/2,v *√ (s₁²/n₁ ) + (s₂²/n₂)

v = degree of fredom    

v  = [ ( s₁²/n₁ + s₂²/n₂)² / (s₁²/n₁)² /n₁-1  + (s₂²/n₂)²/n₂-1

v =  [ (0,86 + 1,45 ) / 0,0043 +  0,017

v = 2,31 / 0,0213

v = 108

Then  t 0,025, 108  from t table is:  We will take v = 100

t = 1,984

Now

√ (s₁²/n₁ ) + (s₂²/n₂)  =  √ 0,86  + 1,43

√ 2,3   = 1,51

Then: CI:

(173 - 127 ) -  1,984*1,51    < μ₁ - μ₂  < ( 173 - 127 )  +  1,984*1,51

46 - 3  < μ₁ - μ₂  < 46 + 3

43 < μ₁ - μ₂  < 49

Sorry if it seems too much to do...
lawyer [7]

Answer:

Step-by-step explanation:

Yikes, that is a lot.

For the first 4 answers. I didn't show my work (sorry :C) but all you really have to do is divide the top number by the bottom number which will give you the decimal, and since a percent is 100x "more" than a decimal, you'll just want to multiply your decimal number by 100.

For 20 and 21 you just need to take the percent, 8% for the first one, 65% for the second one, and put it over 100. After that, simplify the fraction. For the decimal one, just divide the percent number by 100. For 20 you'll get .08, and for 21 you'll get .65 .

22 and 23 are like the first and second parts, but obviously with a decimal instead. It's slightly more tricky, but you just take the part of the decimal and see how much out of 1 it is.

Lytrisha claims that y= 2x2 + 3 is a function but not a linear function select the statement that supports lytrishas claim
Gnom [1K]

Answer:

B

Step-by-step explanation:

A is wrong, it increases

C is wrong, the coefficient does not determine if it is linear (straight), the exponent does.

D is wrong, you don't need to know a point to determine if it is linear, (if you have 3 points you can though. )
