Formula to convert F to C:
(F -32) x 5/9
F = 63 + 10 = 73
73-32 = 41
41 x 5/9 = 22.77777
Rounded to the nearest degree = 23 C

Answer:
We have strong evidence that on average, students study less than 150 minutes per night during the school week
Step-by-step explanation:
Normal distribution:
mean     μ₀ = 150 
Sample:
Sample size    n = 272 
Sample mean   x = 141
Sample standard deviation  s  = 66
The standard error of the sample mean  SE = σ /√n
SE = 66/√272
SE = 66 / 16,49
SE = 4
Test Hypothesis:
Null hypothesis                            H₀             x  =   μ₀ 
Alternative hypothesis                Hₐ            x <    μ₀
z(s)  test statistics is:
z(s)  =  ( x  -  μ₀ ) / s/√n
z(s) = - 9 /4
z(s) =  -  2,25
p-value  for that z(s)      p-value  = 0,0122
Then for α =  0,05 p-value < 0,05
We are in the rejection region we need to reject H₀
