Let
be the average life of light bulbs.
As per given , we have
Null hypothesis : 
Alternative hypothesis : 
Since
is right-tailed and population standard deviation is also known, so we perform right-tailed z-test.
Formula for Test statistic : 
where, n= sample size
= sample mean
= Population mean
=population standard deviation
For
, we have

Using z-value table , Critical one-tailed test value for 0.06 significance level :

Decision : Since critical z value (1.5548) < test statistic (1.6180), so we reject the null hypothesis .
[We reject the null hypothesis when critical value is less than the test statistic value .]
Conclusion : We have enough evidence at 0.06 significance level to support the claim that the new filament yields a longer bulb life

Answer:
Jonah. Five million is a much higher number than 152,000. To put it mathematically -----> 5,000,000 > 152,000.
Step-by-step explanation:
Rounding 5.6192 -
First you look at the hundredth place: If the number is 5 and higher round it up, if its 4 and lower round down. In this case 1 is in the hundredth place which means you round down. So 5.6192 rounded is 5.6
Answer: 5.6 or 5.60
