Answer: 0.0930
Step-by-step explanation:
As per given , we have
H0: μcoffee = 6
Ha: μcoffee < 6
She finds z = −1.68 with one-sided P-value P = 0.0465.
The P-value for two-tailed test is calculated by :

For z= -1.68 , we have

![=2(1-P(z\leq1.68))\ \ [\because\ P(Z>z)=1-P(Z\leq z)]](https://tex.z-dn.net/?f=%3D2%281-P%28z%5Cleq1.68%29%29%5C%20%5C%20%5B%5Cbecause%5C%20P%28Z%3Ez%29%3D1-P%28Z%5Cleq%20z%29%5D)
Hence, the correct two-sided P-value for z = −1.68 is 0.0930 .

the gross pay of Mr. Anderson in a week.
He earns 200 dollars a week + 15% commission on over 1000 dollars sales.
In a week he earned 2500 dollars.
=> Pls, take note, that he can only get a 15% commission for over 1000
dollars sales he get.
=> 2 500 dollars – 1 000 dollars
=> 1 500 dollars, now in 1500 dollars get the 15% commission
=> 1 500 x .15
=> 225 + 200 (his original earnings)
=> 425 dollars.</span><span>
