On solving the provided question, we can say that - Level significance = 0.05, Z = 1.96, Margin of error= 0.0349
A well-known statistical theory called the null hypothesis asserts that there is no statistical connection between two sets of observable data and measurable phenomena for a given set of observed variables. A null hypothesis is a kind of statistical hypothesis that asserts that a certain collection of observations has no statistical significance. Using sample data, hypotheses are tested to determine their viability. Sometimes known as "zero" and symbolized by H0. A scientific hypothesis is a prediction of what researchers will discover via their investigation. A statistical hypothesis, however, states what a statistician does not anticipate. The null hypothesis is so named because of this.
Null hypothesis,
Sample size, n = 570
Sample portion, P’ = 135/579 = .2368
At 95% confidence,
Level significance = 0.05
Z = 1.96
Margin of error= 0.0349
