According to recent UN figures, the annual gun homicide rate is 62.4 per one million residents in the US and 1.3 per one million residents in Britain. Compare the proportion of residents killed annually by guns using the (a) difference of proportions, (b) relative risk. Which measure is more useful for describing the strength of association

Step-by-step explanation:

From the question we are told that

Homicide rate in US

Homicide rate in Britain

Generally the equation for probability of homicide is mathematically given as

Generally the equation for probability of homicide in US is mathematically given as

Generally the equation for probability of homicide in Britain is mathematically given as

a)Generally the difference b/w the probabilities P_D is mathematically given as

Therefore US annual homicide is greater than Britain's

b)Generally the Relative risk is R_r is mathematically given as

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
