A survey was conducted to find out how much time people have to spend commuting to work. The sample means for two samples are 71 and 72 minutes, with p-values of 0.03 and 0.06, respectively. The population mean is μμ. Choose the possible pair of the null and alternative hypotheses. A : H0:μ=80H0:μ=80, Ha:μ<80Ha:μ<80B : H0:μ=60H0:μ=60, Ha:μ>60Ha:μ>60C : H0:μ=71H0:μ=71, Ha:μ>71Ha:μ>71D : H0:μ=72H0:μ=72, Ha:μ<72Ha:μ<72E : None of the above

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:

whats the

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
