Answer:
H0 : σ = 0.5
H0 : σ < 0.5
Step-by-step explanation:
From the scenario described above, the company wants to see conclusive evidence that the population standard deviation of sheath thickness is less than .05 mm ; THIS SIMPLY means ; REJECTION OF the NULL HYPOTHESIS. This is because once there is a significant or conclusive evidence in hypothesis testing, then we reject the null and support the claim of the alternative hypothesis.
Hence, the alternative hypothesis is ; population standard deviation of sheath Thickness is less than 0.5.
H1 : σ < 0.5 ;
Therefore, our null will be ;
H0 : σ = 0.5
Answer:
Step-by-step explanation:
We are told that Nita wants to buy a new keyboard for her computer. She will buy the keyboard when it is on sale for under $50.
Let k be the price in dollars at which Nita will buy the keyboard. Nita will buy the keyboard when its price is less than 50. So we can write our inequality as:
Therefore, our desired inequality will be .
