The image contains questions related to probability and hypothesis testing. I will solve one or more of the listed questions depending on your preference. Let me know which question you'd like me to solve or if you'd like explanations for all of them. Here's a brief overview of the process for solving these:

1. Q1: Hypothesis testing to check if the population mean differs from the sample mean.
2. Q2: Determine if the mean of a sample differs significantly from the population mean.
3. Q3: Testing a hypothesis about the height of individuals in a population.
4. Q4: Test if the breaking strength of metal wires can be considered a specific value.
5. Q5: Test if a drug increases blood pressure.

Let me know where you'd like to start, or if you want to focus on a specific type of test (e.g., t-test, hypothesis test).
