One of your friends is testing the effect of drinking coffee on the duration of cold symptoms. The common cold lasts, on average

Goshia [24]

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 :

$2P(Z>|z|)$

For z= -1.68 , we have

$2P(Z>|-1.68|)=2P(Z>1.68)$

$=2(1-P(z\leq1.68))\ \ [\because\ P(Z>z)=1-P(Z\leq z)]$

$=2(1-0.9535213)\ \ \ [\text{ NORM.S.DIST(z, TRUE}]\\\\=2( 0.0464787)=0.0929573\approx0.0930$

Hence, the correct two-sided P-value for z = −1.68 is 0.0930 .
