N a genetics lab, 65 fruit flies were sampled for the amount of time it takes for them to mature into fully grown adult flies. The test showed an average time of 18.5 days for this to happen. If the data follows a normal distribution with a standard deviation of 59 hours, find the 95% confidence interval for the true mean of the dataset. (Hint: Make sure that the unit of measurements are the same for the given paramete

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

pretty sure 750 each month!

step-by-step explanation:

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
