The number of variables in a hypothesis test typically depends on the research question being addressed and the complexity of the relationship being studied. In general, it is recommended to include only the necessary variables that directly relate to the hypothesis being tested to minimize confounding factors and improve the clarity of results.
The two parts of a hypothesis are the null hypothesis, which states that there is no significant difference or relationship, and the alternative hypothesis, which suggests that there is a significant difference or relationship between variables.
To come up with a hypothesis for a lab experiment, you need to make an educated guess or prediction about the relationship between two variables in the experiment. Review background research, identify the independent and dependent variables, and consider how changes in the independent variable might affect the dependent variable. Formulate a concise statement that captures this relationship and serves as the basis for your experiment.
The number of variables that can be tested at a time may vary depending on the experimental design and resources available. In practice, it is common to test one to three variables simultaneously in order to effectively analyze and interpret the results. However, some experimental designs may allow for testing more variables at once.
It means there is no reason why he should reject it, whether because there is no evidence to the contrary or because an experiment set up to test it affirmed that hypothesis.
The results in the scientific method are based on observations and experiments that are conducted to test a hypothesis. Scientists collect and analyze data to draw conclusions about the relationship between variables and to determine if the hypothesis is supported or refuted. These results are then used to either confirm or refine existing scientific knowledge.

Test your hypothesis against the available data
To turn a simple hypothesis into a testable one, you need to clearly define the variables, identify the specific relationship between them, and determine how you will measure or observe those variables in an experiment. This involves operationalizing the variables and outlining the methods you will use to collect data in order to test the hypothesis. Finally, ensure that your testable hypothesis is specific, falsifiable, and feasible to investigate.
One way to test a hypothesis is to conduct an experiment where you manipulate the variables of interest and observe the outcomes. Ensure that the experiment is well-designed, with appropriate controls and replicates, to draw valid conclusions about the hypothesis. Analyze the data collected using statistical methods to determine whether the results support or refute the hypothesis.
That would depend on your hypothesis!
There can only be one independent and one dependent variable. All other variables should be classed as control variables and must be kept constant to achieve a fair test.

In statistics, a null hypothesis is the hypothesis which you wish to test against some alternative. Often, it is framed in a way that is the opposite of what you wish to prove. You then collect the data and, if the resulting test statistic is such that observations which are at least as extreme as the one realised is very unlikely under the null hypothesis, then it is rejected and the alternative accepted.
