Answer: p-value= 0.5686
Explanation:
11% = 11/100 = 0.11
Null hypothesis is p = 0.11
Alternative hypothesis is p ≠ 0.11
Therefore, this test is a two tailed test.
Given,
Null parameter, P,= 0.11
Sample Statistics, Phat, = 8/88 = 1/11
= 0.09091
n = 88
z= (sample statistics - Null parameter) ÷ SE
z = (phat - p)/√[p(1-p)/n]
z = (0.09091 - 0.11)/ √[0.11(1-0.11)/88]
z = - 0.019091 ÷ √0.0011125
z = - 0.019091 ÷ 0.033354
z = - 0.572375
Z ≈ - 0.57
According to the table
z = -0.57 = 0.2843
Since it's a two tailed test,
Therefore,
p value = 2 x 0.2843 = 0.5686
Answer:
Explanation:
Body fluid contains electrolytes, chemicals which, when they dissolve in water, produce charged ions. These ions enable the flow of electrical signals through the body. Electrolytes play an important role in the body; they regulate the osmotic pressure in cells and help maintain the function of muscle and nerve cells.
Is it multiple answer?? Because if so I would pick b and d
