$\frac{2}{3}+\frac{1}{4}$

Re-write with a common denominator, in this case 12:

$\frac{2 \times 4}{3 \times 4}+\frac{1 \times 3}{4 \times 3}$
$\frac{8}{12}+\frac{3}{12}$

Add:
$\frac{8}{12}+\frac{3}{12} = \frac{11}{12}$

1/2 (3/2 y + 1/3) = -1/2 (y- 5/2)

dem82 [27]

1/2 [ (3/2)y + 1/3] = -1/2 [y-5/2]

(3/2)y + 1/3 = -(1/2)y + 3

(3/2 + 1/2)y = 3 - 1/3

2y = 8/3

y = 4/3

y = 1.33

Answer: One tail test.

Step-by-step explanation:

Given : A sample of 36 observations is selected from a normal population. The sample mean is 12, and the population standard deviation is 3.

Also, The set of hypothesis to conduct a test :-

$H_0:\mu\leq10\\\\H_1:\mu>10$

The kind of test need to perform is dependent upon the alternative hypothesis.

Since, the alternative hypothesis is one tailed (right-tailed), so the test is one tail test.

1.theoretical is not counting the results of the experimentssince there are an equal number of red and black and red, the probblity (theoretical) of picking a black one is 1/3
experimental=number of outcomes happened/total number of tests4 times black, 4 tests, so 4/4 or 100%=experimental proablity

2. experimental considered previous trials and theoretical did not

3. theoretical=(1/4) the trials don't influence each other so1/(4*4)=1/16
