Step-by-step explanation:
Answer:
0.13093
Step-by-step explanation:
Give. That :
Population mean = 40% = 0.4
Sample size (n) = 64
Probability that more than 30 have computer at home
Mean = np = 64 * 0.4 = 25.6
Standard deviation = sqrt(n*p*(1-p)) = 3.919
P(x > 30)
USing the relation to obtain the standardized score (Z) :
Z = (x - m) / s
Z = (30 - 25.6) / 3.919 = 1.1227353
p(Z < 1.122) = 0.13093 ( Z probability calculator)
Answer:
40 % increase
Step-by-step explanation:
percent increase = (new - original)/ original
percent increase = (35-25)/25
= 10/25
=.4
multiply by 100
40 percent
It is 32.0173263 because you add spaces to the decimal point and of course you don't put the zeros in
