There are 82 boats in the navy. 48 of them are battleships and the rest are destroyers. What is the ratio of the number of destroyers to the number of battleships?
Let
x -----> the number of destroyers
y ----> the number of battleships
the ratio is
x/y
we have
y=48
x=82-48=34
therefore
ratio=34/48
simplify
34/48=17/24
answer is 17/24 or 17:24
To solve this, we need to use the z test. The formula for
z score is:
z = (x – u) / s
where x is sample value = 141.4 mm and above, u is mean
value = 140 mm, s is standard dev = 8 mm.
z = (141.4 – 140) / 8
z = 0.175
From the standard probability tables, the p value at z =
0.175 using right tailed test is:
P = 0.4306
