Ratio equivalent to 12:3

= 12:3

= 12/3 (.°.3x4= 12 and 3x1=3)

= 3x4/3x1 (.°. cancellation of 3 from numerator and denominator)

= 4/1

likewise, 4:1 , 60:15 , 84:21 , 132:33..............etc no. of ratios are equivalent to 12:3

.°. Required ratios which are equivalent to 12:3 are4:1 , 60:15 , 84:21 , 132:33..............etc

Answer:

The p-value would be 0.0939

Step-by-step explanation:

We can set a standard t-test for the Null Hypothesis that $H_0: 18.2\geq 17$

The test statistic then takes the form

$t=\frac{18.2-17}{3.9/\sqrt{15}}=1.317$

with this value we then can calculate the probability that is left to the right of this value $P(X>1.317)$ . From theory we know that t follows a standard normal distribution. Then $P(X>1.317)=0.0939$ which is smaller than the p-value set by Breyers of 0.10

The probability for the z-score is greater than or equal to 1.4 is 0.08076 or 8.076 %.

<h3>What is a z-score?</h3>

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

The probability for the z-score is greater than or equal to 1.4 is given as

P(z ≥ 1.4) = 1 - P( z < 1.4}

P(z ≥ 1.4) = 1 - 0.91924

P(z ≥ 1.4) = 0.08076

P(z ≥ 1.4) = 8.076 %
