Explanation Given info: A random sample of 600 people has been taken by the radio station to know the number of residents who heard the ads of the station. Calculation: The test hypotheses are given below: Null hypothesis: H 0 : p = 0.20 _ That is, the proportion of residents heard the advertisement of the radio station and remembers the product is 0.20. Alternative hypothesis: H A : p > 20 _ That is, the proportion of residents heard the advertisement of the radio station and remembers the product is greater than 0.20. Verify the condition: Independence assumption: It is reasonable to assume that the residents are independent of one another in remembering the ad. Randomization condition: The sample of 600 residents was selected at random. Success/failure condition: n p 0 ≥ 10 , n q 0 ≥ 10 Condition 1: n p 0 = ( 600 ) ( 0.20 ) = 120 ( > 10 ) Condition 2: n q 0 = ( 600 ) ( 0.80 ) = 480 ( > 10 ) Here, n p 0 and n q 0 are greater than 10. Hence, the success/failure condition is satisfied. 10% condition: Size of 600 is less than the 10% population of city. Thus, the condition is satisfied b.

Addition Rule of Probability

It simply refers to the likelihood of an event taking place whenever the occurrence of an event is uncertain. The probability of a single event can be calculated by dividing the number of successful trials of that event by the total number of trials.

Expected Value

When a large number of trials are performed for any random variable ‘X’, the predicted result is most likely the mean of all the outcomes for the random variable and it is known as expected value also known as expectation. The expected value, also known …

Probability Distributions

Understanding probability is necessary to know the probability distributions. In statistics, probability is how the uncertainty of an event is measured. This event can be anything. The most common examples include tossing a coin, rolling a die, or choosi…

Basic Probability

The simple definition of probability it is a chance of the occurrence of an event. It is defined in numerical form and the probability value is between 0 to 1. The probability value 0 indicates that there is no chance of that event occurring and the prob…
