The average systolic blood pressure was found to be 140 mm for people who have high responsibility jobs, specifically investment
9966 [12]

Answer:

Option B)

H_{0}: \mu = 140\text{ mm}\\H_A: \mu < 140\text{ mm}

Step-by-step explanation:

We are given the following in the question:

Hypothesis:

The doctors and u=instructor claims that practicing yoga reduces blood pressure and hence is beneficial to people.

Population mean, μ =  140 mm

Sample mean, \bar{x} =  139 mm

Sample size, n = 51

Sample standard deviation, s = 5 mm

Thus, we can design the null hypothesis and alternate hypothesis as

H_{0}: \mu = 140\text{ mm}\\H_A: \mu < 140\text{ mm}

The null hypothesis states that the population have a blood pressure of 140 mm. The alternate hypothesis states that yoga reduces the blood pressure and the sample has a blood pressure less than 140 mm.

Thus, the correct answer is

Option B)

H_{0}: \mu = 140\text{ mm}\\H_A: \mu < 140\text{ mm}

Every orthogonal matrix is diagonalizable. O True O False
Simora [160]

Answer:

FALSE

Step-by-step explanation:

the correct answer is FALSE

A matrix is said to be orthogonal when it is  multiplied by its own transpose then the matrix comes out to be Identity.

                                      A^T.A = I

the basic condition for a matrix to be diagonalizable is that the matrix should be symmetric.

but an orthogonal matrix is not necessarily symmetric so, the statement is false.
