Answer:
Step-by-step explanation:
7 friends plus himself = 8 persons
Round trip flight cost = &389x8= & 3112
Hotel bill = &249 x 4 rooms 3 nights = &
& 2988
Cost at Observatory desk = & 18.5 x 8= & 148
Cost at base ball viewing venue = 38 x 8 = & 148
Total budget apart from feeding should be = & 6552
The z-score is given by:
z=(x-mean)/s.d
the z-score giving us P(0.95)=1.96 and -1.96
thus;
-1.96=(x-1500)/300
-588=x-1500
x=-588+1500
x=912
also:
1.96=(x-1500)/300
588=x-1500
x=588+1500
x=2,088
therefore the sample size of the student picked will be given by:
2,088-912
=1,176
The answer would be 78 and 80 because it between those two numbers
