Hello There!
<u><em>The number of adult tickets sold in the school play = 225</em></u>
<u><em></em></u>
<u><em>Total Number Of Tickets = 505</em></u>
<u><em>Number Of Student Tickets = x + 55</em></u>
<u><em></em></u>
Number of adult tickets sold can be represented by X
Number of student tickets = X + 55
X+X+55=505
2x+55=505
2x=505-55
2x=450
X=225

Answer:
Step-by-step explanation:
Given that for a sample size of 25, sample mean = 102 lbs. and sample std deviation = 10 lbs.

(Right tailed test)
Given that we assume population is normally distributed
Test statistic:
Mean difference = +2
Std error of sample = 
t = test statistic = Mean diff/Std error 
degree of freedom
Critical value of t = 1.711
Our test statistic >1.71
Accept alternate hypothesis
Because there is significant difference between the test statistic and test statistic lies above critical value.
