John left accra at 10: 45am and reached freetown at 16: 50pm. how long did the journey last?

6hrs 5min

Step-by-step explanation:

Military time.

10:45 to 11:45= 1hr

10:45 to 12:45= 2hr

10:45 to 13:45 ( 1:45)= 3hr

10:45 to 14:45 (2:45)= 4hrs

10:45 to 15:45 (3:45)= 5hrs

10:45 to 16:45 (4:45)= 6hrs + 5min= 6hrs n 5min

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;
