Here are six measurements of the electrical conductivity of an iron rod. 10.02 9.83 9.99 10.10 10.15 10.05
The iron rod is supposed to have conductivity 10.1. Do the measurements give good evidence that the true conductivity is not 10.1?
The six measurements are an SRS from the population of all results we would get if we kept measuring conductivity forever. This population has a Normal distribution with mean equal to the true conductivity of the iron rod and standard deviation 0.1. Use this information to carry out a test, following the four-step process.
A) SOLVE: Assume that we have an SRS from a Normal population. Calculate the test statistic. (Round your answer to two decimal places.)
z=
B) SOLVE (continued): What is the P-value for the test? (Round your answer to four decimal places.)
z=

this is a very good question

step-by-step explanation:

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
