Null hypothesis: Television advertising has the same influence on athletic shoe sales as advertisements found in magazines.

You first decide on a null hypothesis. Expected frequencies are calculated on the basis of the null hypothesis, that is, assuming that the null hypothesis is true.
A statistician may have some idea about some statistics in a data set, and there is a need to test whether or not that hypothesis is likely to be true. Data are collected and a test statistic is calculated. The value of this test statistic is used to determine the probability that the hypothesis is true.
In experimental design, the null hypothesis serves as a foundational statement that posits no effect or no difference between groups or conditions. It provides a baseline against which researchers can compare their experimental results. By testing the null hypothesis, researchers can determine whether observed effects are statistically significant or could have occurred by chance. If the null hypothesis is rejected, it suggests that there is enough evidence to support an alternative hypothesis.
They should go back to the theories on which the hypothesis was based and determine which of them was most likely to have been wrong. This should be followed by either coming up with a modification of the theory or the development of a new theory.
No one really can determine how much, its mostly up to the station that you will advertise on
The purpose of a Nielsen rating is to measure the audience size and demographic information for television programming. It provides valuable data to television networks, advertisers, and content creators to understand viewership trends and make informed decisions about programming and advertising strategies.
To determine the inverse, negate both the hypothesis and conclusion.
Test your hypothesis by Doing an Experiment
The significance test is the process used, by researchers, to determine whether the null hypothesis is rejected, in favor of the alternative research hypothesis, or not.
To determine if your hypothesis is right
A testable hypothesis is one where you can experimentally manipulate variables in order to determine the veracity of the hypothesis.
The q-value formula in statistical hypothesis testing is used to calculate the false discovery rate of a set of hypothesis tests. It helps determine the likelihood of falsely rejecting a true null hypothesis.
that depends on exactly what the hypothesis is. You cannot determine if something is right or wrong by who made the hypothesis.
Concluding that the hypothesis is correct based on personal beliefs or opinions is not part of testing a hypothesis. Testing a hypothesis involves designing experiments, collecting data, and analyzing results to determine if the hypothesis is supported or not.
the optimal level of advertising expenditure for the firm is determined where the marginal revenue increase in costs of advertising are equal to the marginal increase in revenue
