AP Statistics Quiz 10.2
guapka [62]

Answer:

Hello some data related to your question is missing attached below is the missing data

a) we will reject the null hypothesis hence it can be determined that the salary of politicians is greater than that of EMTs through the use of two-sample t procedures. since ( to > critical value )

b) <em>( 3.819 , 8.5226 ) </em>

Step-by-step explanation:

Applying the Given data:

The test hypothesis :

H0 : μ1 = μ2

Ha : μ1 > 2

A) since ( to > critical value ) we will reject the null hypothesis hence it can be determined that the salary of politicians is greater than that of EMTs through the use of two-sample t procedures

B ) construct and interpret

next calculate the SP value

S^{2} _{p} = \frac{( n1 - 1 )S^{2} _{1} + ( n_{2}- 1 )S^{2} _{2}    }{n1 + n2 - 2}

where: S1 = 7524 , n1 = 50 , n2 = 100 , S2 = 5551   ( input values into equation above )

∴ S^{2} _{p} = 39354491.3716

hence : S_{p} = 6273.32

next calculate the value of test statistic

to = ( X1 - X2 - Δo ) / Sp \sqrt{\frac{1}{n1} + \frac{1}{n2}  }

where: X1 = 61234 , X2 = 54529 , Sp = 6273.32 , n1 = 50 , n2 = 100  ( input values into equation above )

to = 6705 / 1086.5702 = 6.1708

Df ( degree of freedom ) = n1 + n2 - 2 = 148

critical value at ∝ = 0.01  = ± 2.3518  ( using excel function : T.INV(0.01,148) )

hence the confidence Interval

= ( 6.1708 ± 2.3518 )

<em>= ( 3.819 , 8.5226 ) </em>
