Let
be the number of students who eat cauliflower.
Therefore,
.
Let
be the total number of students surveyed.
Therefore, 
Thus, 

Now, for 90% confidence level, from the table we know that
.
The formula for the interval range of proportion of students is :

Plugging in the values we get:

Thus, Jane is 90% confident that the population proportion p, for students who eat cauliflower in her campus is between 5.398% and 15.114% (after converting the answer we got to percentage).
1.2 + d + 0.4 = 9.7
1.6 + d = 9.7
1.6 (-1.6) + d = 9.7 (-1.6)
d = 8.1
your answer is 8.1
