Answer:
The greater the sample size the better is the estimation. A large sample leads to a more accurate result.
Step-by-step explanation:
Consider the table representing the number of heads and tails for all the number of tosses:
Number of tosses n (HEADS) n (TAILS) Ratio
10 3 7 3 : 7
30 14 16 7 : 8
100 60 40 3 : 2
Compute probability of heads for the tosses as follows:

The probability of heads in case of 10 tosses of a coin is -0.20 away from 50/50.

The probability of heads in case of 30 tosses of a coin is -0.033 away from 50/50.

The probability of heads in case of 100 tosses of a coin is 0.10 away from 50/50.
As it can be seen from the above explanation, that as the sample size is increasing the distance between the expected and observed proportion is decreasing.
This happens because, the greater the sample size the better is the estimation. A large sample leads to a more accurate result.
Answer:
So the value of the test statistic is -0.85.
Step-by-step explanation:
We know that a sample of 1800 computer chips revealed that 53% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 54% of the chips do not fail in the first 1000 hours of their use.
We get that:

We calculate the standar deviation:

We calculate the value of the test statistic:

So the value of the test statistic is -0.85.
Answer:
n= 100
Step-by-step explanation:
Product is the answer when two numbers are multiplied together. So, n×-6=600.
100×-6=-600
Answer:
C. Solving this equation results in the statement –48 = 48. Because this is a false statement, the equation has no solution.
