9. A car is being tested for reliabi ty on a track by driving at a constant speed. The car has traveled 150 miles in 3 hours. a. Complete the table below Distance (mi) Song 150 2002 Time (hr) 1 2 3 4 5 b. If the car breaks down 4.5 hours into the test and has to stop for a repair before continuing, what ratio(s) of distance to time would be affected? c. How would you expect the ratio to change? Explain your reasoning.​

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.

step-by-step explanation:

step-by-step explanation:

no of data

divide by no of mode

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
