Answer:
Test statistic Z= 0.13008 < 1.96 at 0.10 level of significance
null hypothesis is accepted
There is no difference proportion of positive tests among men is different from the proportion of positive tests among women
Step-by-step explanation:
<em>Step(I)</em>:-
Given surveyed two random samples of 390 men and 360 women who were tested
first sample proportion
second sample proportion
Step(ii):-
Null hypothesis : H₀ : There is no difference proportion of positive tests among men is different from the proportion of positive tests among women
Alternative Hypothesis:-
There is difference between proportion of positive tests among men is different from the proportion of positive tests among women
where
P = 0.920
Test statistic Z = 0.13008
Level of significance = 0.10
The critical value Z₀.₁₀ = 1.645
Test statistic Z=0.13008 < 1.645 at 0.1 level of significance
Null hypothesis is accepted
There is no difference proportion of positive tests among men is different from the proportion of positive tests among women
Answer:
265 BOXES /4 BOTTLES WILL BE WITHOUT BOXES
Step-by-step explanation:
I SUBTRACTED 2136 FROM 8500. IT GAVE ME 6364. THE I TRIED TO DEVIDE BY 24 BECUASE ITS THE NUMBER OF BOTTLES IN A BOX. IT GAVE A MIXED NUMBER WICH IS 265.16 TERMINATING. I TRIED TO DEVIDE 6360 INSTAID OF 6364 AND IT GAVE 265 AND THE REMAINDER WAS 4.

Answer:
he bought three math books and four english books
Step-by-step explanation:
26x3=78 (three books)
28x4=112 (four books)
112+78=190
For the answer to the question above, you will find probabilities for continuous r.v.'s like P(a < X < b) you just find the area under the density curve (what you have called the distribution). In this case, that's finding the area of a rectangle which means that if you can calculate sq ft for carpeting, you can do this problem.
For example,
<span>e) (0.76 - 0.23)*1 = 0.53
</span>
For this problem t<span>he answer is the area above the interval:
eg. the probability of a) is 0.4 x height or 0.4 x 1 = 0.4. </span>
I hope I helped you with my answer
Answer:
(-2,4)
Step-by-step explanation:
The solution to the system is where the two lines intersect
The lines intersect at x = -2 and y = 4
