One astronomical unit is about 93,000,000 miles. At 20,000 miles per hour, how many astronomical units can Orion travel in one h

Olenka [21]

Answer:

$\frac{1}{4,650}\ astronomical\ unit$

or

$2.15*10^{-4}\ astronomical\ unit$

Step-by-step explanation:

we know that

One astronomical unit is about 93,000,000 miles

so

using proportion

Find out how many astronomical unit represent 20,000 miles

Let

x ----> the number of astronomical unit

$\frac{1}{93,000,000} =\frac{x}{20,000}\\\\x=\frac{20,000}{93,000,000}\ astronomical\ unit$

simplify

$\frac{1}{4,650}\ astronomical\ unit$

or

$2.15*10^{-4}\ astronomical\ unit$

Is the statement H0 : µ = 9 a valid null hypothesis? Group of answer choices Yes, this is a statement that compares a parameter

Nuetrik [128]

Answer:

No, there is no parameter contained in this statement

Step-by-step explanation:

Given that H0 : µ = 9

We have to check whether this is a valid null statement

Normally null hypothesis would have equal to sign and the value to be tested would be a statistic i.e. a measure characteristic of a sample.

So we create null hypothesis as sample mean = 9 or \mu or sample std deviation and so on.

Here population parameter mu is equated to 9

Hence not a valid null hypothesis.

No, there is no parameter contained in this statement
