Explanation / Answer

Null Hypothesis ,there Is No-Significance between them Ho: natural – artificial=0
Alternate Hypothesis ,there is support that natural light is better H1: natural – artificial>0

For t-test statistic is -5.8 We reject the Ho AT 95%,99%, 90% C.I

b.  
Reject the null and conclude there is support that natural light is better
