Answer:
95% confidence interval = ( 28.9485, 40.1515 )
Step-by-step explanation:
sample size( n ) = 52
mean value ( x )= 34.55
std ( б ) = 20.12
H0 : <em>u </em>≤ 30
Ha : u > 30 ( claim )
95% confidence interval for mean SPF level ( df = 51 )
= mean value ± 
95% confidence interval = ( 28.9485, 40.1515 )
we cannot reject H0
