Hypothesis:

n₁ = 100
x₁ = 37
So, 
n₂ = 100
x₂ =47
So, 
At 0.01 level of significance, z = 2.33
So, test statistic value would be

Since, 2.33>-1.44
Hence, we will reject the null hypothesis.
Therefore, Yes, this indicate the proportion of adult americans that attended college and believe in extraterrestrials is higher than the proportion that did not attend college
