![It was reported that 46% of people believe that there is life on
other planets in the universe. A scientist does not agree with
this finding. He surveyed 120 randomly selected people and found
that 48 believed that there is life on other planets. Test the
null hypothesis that the population proportion is 0.46 against
the alternative hypothesis that it differs from 0.46, at the
0.10 level of significance.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1ef892af-4acd-4196-b073-229ef6fba333%2F668717e6-53cb-4b94-b1eb-a246158abbe5%2Fj00idza_processed.png&w=3840&q=75)

1. The null hypothesis is defined as the test conducted under homogeneous conditions for its possible rejection under the assumption that it is true. It can be one-tailed to two-tailed. The null hypothesis is generally denoted as H0. It states the exact opposite of what an investigator or an experimenter predicts or expects. It basically defines the statement which states that there is no exact or actual relationship between the variables.
In this case, the null hypothesis H0: The population proportion 'p' is 0.46
2.Any alternate statement to the null hypothesis is the alternative hypothesis. The alternative hypothesis is generally denoted as H1. It makes a statement that suggests or advises a potential result or an outcome that an investigator or the researcher may expect. It has been categorized into two categories: directional alternative hypothesis and non-directional alternative hypothesis.
In this case, the alternative hypothesis is H1: The population proportion differs from 0.46 i.e.
