Answer:
b) yes
The manufacturer has the right to state that the light bulbs last on average 400 hours
Step-by-step explanation:
<u><em>Explanation:-</em></u>
<em>Given sample size 'n' = 64</em>
<em>Given standard deviation of the Population (σ)=100</em>
<em>Mean of the sample (x⁻) = 350 hours</em>
<em>95% of confidence interval is determined by</em>
(
(350-24.5 , 350+24.5)
<em>(325.5 , 374.5)</em>
<u><em>Conclusion:-</em></u>
<u><em>Yes</em></u>
The manufacturer has the right to state that the light bulbs last on average 400 hours
Answer:
2550 miles in 6 hours
Step-by-step explanation:
if you divide the miles and hours by each other you will get the m/ph (miles per hour)
3400 ÷ 8 = 425
now, that we know the plane travels 435 m/ph, then if we multiply it by 6 we will get the answer
425 × 6 = 2550
Answer:
1. i Sampling bias and
ii. Question order bias
2. Non response Bias
3.i. sampling bias
ii.question order bias
4. i. response bias
ii.sampling bias
Step-by-step explanation:
we have basically four types of bias in a research which are;
1. Sampling bias
2. Response bias
3. Non response bias
4. Question order bias
The equation is true because both sides are identical.
