Answer:
0.00002
Step-by-step explanation:
Think of 2 as 2.0
Now, base ten with a negative exponent means moving the decimal point in the multiplied number to the left, where as base ten with a positive exponent means moving the decimal point in the number to the right. The empty spaces are filled with zeros.
So, in 2.0, the decimal is moved to the left 5 times, because the exponent is -5, and the empty spaces are filled with 0. Once to the left is 0.2, twice is 0.02, thrice is 0.002, four times is 0.0002, and five times is 0.00002
That's It!

Answer:
0.017559
Step-by-step explanation:
Data provided:
Probability of Households Having cable TV, p₀ = 76% = 0.76
Therefore,
The probability that the Households not having cable TV = 1 - 0.76 = 0.24
Sample size, n = 225 households
sample proportions is less than 82% i.e p = 0.82
Now,
The standard error, SE = 
or
SE = 
or
SE = 0.02847
and,

or

or
Z = 2.107
therefore,
P(sample porportions < 0.82) = P(Z < 2.107)
now from the p value from the Z table
we get
P(sample porportions < 0.82) = 0.017559
