The mean height of a certain kind of plant is 171 centimeters. Suppose we want to carry out a hypothesis test to see if the mean

height when these plants are treated with a certain chemical differs from 171. State the null hypothesis and the alternative hypothesis that we would use for this test.

Answer:

Null Hypothesis: H_0:\mu=171

Alternative Hypothesis: H_1:\mu\neq 171

Step-by-step explanation:

It is given that the mean height of a certain kind of plant is 171 centimeters.

Null Hypothesis: A hypotheses of no statistical significant difference is known as null hypothesis. The null hypotheses for this test is

H_0:\mu=171

Alternative Hypothesis: If a hypothesis is used in hypothesis testing that is contrary to the null hypothesis is known as alternative hypotheses. The alternative hypotheses for this test is

H_1:\mu\neq 171

A suitcase measures 24 inches long and 18 inches high, what is the diagonal length of the suitcase?
pickupchik [31]

Answer:

The diagonal is 30 inches

Step-by-step explanation:

Assuming a rectangular suitcase (with right angles), we can use the Pythagorean theorem to solve this

a² + b² = c²

so we plug our two values to find the diagonal (hypotenuse)

24² + 18² = c²

576 + 324 = c²

900 = c²

c = √900

c = 30

The diagonal is 30 inches

30. Each interior angle of a regular polygon is 4 times each exterior ang
kifflom [539]

Answer:

(a) the size of each exterior angle  360/10=36

(b)  the number of sides of the polygon.​ 10

Step-by-step explanation:

Each interior angle of a regular polygon is 4 times each exterior angle

∴sum of interior angles: (n-2)*180=4*360

n-2=8

n=10

(a) the size of each exterior angle  360/10=36

(b)  the number of sides of the polygon.​ 10

The volume of a right cone is 3525\piπ units^3
Greeley [361]

The height of the right cone given its volume and its diameter is  47 units.

<h3>What is the height?</h3>

A cone is a three-dimensional object that has a circular base and a vertex.

Height of the cone = Volume of a cone ÷ 1/3(πr²)

Where:

  • π = 22/7
  • r = radius = diameter / 2 = 30 / 2 = 15 units
  • h = height

3525π÷ (1/3 x π x 15²) = 47 units
