Who runs faster ? HELP

Mathematics
1 answer:
Lady bird [3.3K]4 years ago
4 0

To find the answer, we can first convert all their speed to feet per second.

Also note that:

1 miles = 5280 feet

1 minute = 60 seconds

We can then proceed to find the answer:

Debbie: 10 ft/s

Stephanie: 131/10 = 13.1 ft/s

Jessica: 1x5280/440 = 12ft/s

Ron: 547/1x60 = 9.1166..ft/s

Therefore, Stephanie has the highest speed (13.1 ft/s)

Hope it helps!

bazaltina [42]

Answer:

a) H0: p > 0.0016

H1: p ≤ 0.0016

Step-by-step explanation:

A null hypothesis states that there is no relation between two variables, it's what the researcher wants to discredit.

On the other hand, the alternative hypothesis is what the researcher tries to prove.

<u>The claim of this entomologists is that fewer than 16 in ten thousand male fireflies are unable to produce light due to a genetic mutation. Therefore, this claim is what he wants to prove and it would be the alternative hypothesis.</u>

H1: p ≤ 0.0016

The null hypothesis would be the opposite of the alternative hypothesis and therefore it would be:

H0: p > 0.0016
