Harvey the wonder hamster can run 3\dfrac16 \text{ km}3 6 1 km3, start fraction, 1, divided by, 6, end fraction, space, k, m in \dfrac14 4 1 start fraction, 1, divided by, 4, end fraction hour. harvey runs at a constant rate. find his average speed in kilometers per hour.

Given the distance the wonder hamster run = 3 1/6 km.

Time in hours = 1 1/4 hours.

We need to find the average speed of Harvey in kilometers per hour.

We know speed formula

Speed = distance/time.

Plugging value of distance and time in above formula, we get

Average speed = 3 1/6 ÷ 1 1/4

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;
