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 ± $(2.0076 + \frac{20.12}{\sqrt{52} } )$

95% confidence interval = ( 28.9485, 40.1515 )

we cannot reject H0

7 × (7+x) = 8 × (8+13)

49 + 7x = 8 × 21 = 168

7x = 119

x = 17
