Breyers is a major producer of ice cream and would like to test the hypothesis that the average American consumes more than 17 o

zhenek [66]

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 sum of the lengths of any two sides of a triangle must be greater than the third side. if a triangle has one side that is 8

BartSMP [9]

1st Side: 8

2nd Side: 2x - 1

3rd Side: x

(8) + (2x - 1) > x (2x - 1) + x > 8 (x) + (8) > 2x - 1

2x + 7 > x 3x - 1 > 8 8 > x - 1

2x > -7 3x > 9 9 > x

x > -3.5 (disregard) x > 3 x < 9

3rd Side: x ⇒ (3 < x < 9)

2nd Side: 2x - 1 ⇒ 2(3) - 1 < x < 2(9) - 1 ⇒ 5 < x < 17

Answer: the 3rd side must be between 3 and 9, the 2nd side must be between 5 and 17
