It's B. the sides of a square have to be equal, so you can check by squaring any of the options and seeing which ones equal 225. 15 is the square root of 225. this can be expressed as 15=sqrt225

mixer [17]

Answer:

0.060

Step-by-step explanation:

In a two tailed test the probability of occurrence is the total area under the critical range of values on both the sides of the curve (negative side and positive side)

Thus, the probability values for a two tailed test as compared to a one tailed test is given by the under given relation -

p-value = P(Z< -\frac{\alpha }{2} )+P(Z >\frac{\alpha}{2})\

Here P\frac{\alpha}{2} = 0.030

Substituting the given value in above equation, we get -

probability values for a two tailed test

=0.030 + 0.030\\= 0.060
