an automobile manufacturer claims that their tires last more than 70,000 miles before replacement? Whats the null and alternative hypothesis
Ho: x ≥ 70,000
Ha: x < 70,000
Ho: x > 70,000
Ha: x ≤ 70,000
To determine the null and alternative hypothesis for the claim made by the automobile manufacturer, we need to frame the hypotheses in a statistical context.
Null Hypothesis (H₀): The average tire lifespan is equal to or less than 70,000 miles.
Alternative Hypothesis (H₁): The average tire lifespan is more than 70,000 miles.
In this case, we are testing whether the manufacturer's claim holds true (alternative hypothesis) or not (null hypothesis) based on statistical evidence.
