The
formula for the population proportion is:
n = p ± Zc
where p =
confidence level = 0.2
n =
proportion = 0.22
= standard error = 0.01
Finding for Zc:
.20+(.01)=.22
Zc = 2
Referring to Critical value table for standard
normal curve, a Zc value of 2 is equivalent to 95% Confidence Level.
Answer: 95% Confidence Level

Volume of sphere = 4/3*pi*r^3
34500 = 4/3*pi*r^3
25875 = pi*r^3
8240.445 = r^3
r = 20.2
The company spends $649 on advertising
The sales function after advertising is given as:
When the total sales is $19,100, we have S(x) = 19100
So, the sales function becomes
Subtract 5 from both sides
Divide both sides by 7
Take exponents of both sides
Subtract 1 from both sides
Hence, the company spends $649 on advertising
