The mean height of a certain kind of plant is 167 centimeters. Suppose we want to carry out a hypothesis test to see if the mean height when these plants are treated with a certain chemical differs from 167. State the null hypothesis \( H_0 \) and the alternative hypothesis \( H_1 \) that we would use for this test.**Hypotheses:**\( H_0: \) \( H_1: \) **Symbols and Operators:**The diagram on the right shows a selection of statistical symbols and operators. These include:- \( \mu \): Population mean- \( \overline{x} \): Sample mean- \( p \): Population proportion- \( \hat{p} \): Sample proportion- \( \sigma \): Population standard deviation- \( s \): Sample standard deviationOperators for constructing expressions include:- \( = \): Equals- \( \neq \): Not equal to- \( < \): Less than- \( > \): Greater thanThe task requires selecting the appropriate symbols and operators to fill in the hypotheses for testing the effect of the chemical treatment on plant height.

Test is that whether the mean height of the plants when treated with a certain chemical differs from…

Suppose there is a claim that a certain population has a mean, µ, that is different than 7. You want to test this claim. To do so, you collect a large random sample from the population and perform a hypothesis test at the 0.05 level of significance. To start this test, you write the null hypothesis H, and the alternative hypothesis H, as follows. Hoi u= 7 H: u =7 Suppose you also know the following information. The critical values are - 1.960 and 1.960 (rounded to 3 decimal places). The value of the test statistic is 2.477 (rounded to 3 decimal places).
