While imprisoned by the Germans during World War II, the English mathematician John Kerrich tossed a coin 10,000 times and obtained 5,067 heads, resulting in an experimental probability ofp = 50.67% that the coin would land heads-up on a single toss. Let p be the true probability of heads on a single toss. We wish to check if Kerrich's data are consistent with the hypothesis that the coin is fair (ie., p = 0.50) a. Set-up the null and alternative hypotheses. H. XR
b. Calculate the test statistic, zo
c. Calculate the P-value.

step-by-step explanation: yes

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

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.

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2
