Answer:

Step-by-step explanation:

Hello!!!

from the problem statement we can infer that Jamal had a container of water where he fetches from to fill the graduated cylinder.

More so, after some couple of trails he recorded as follows

25.85, 24.1, and 24.56.

Hence the total amount of water he measured out of the container after three trials is

25.85+24.1+24.56= 74.51 ml

(assuming the cylinder is calibrated in ml)

<em>The total volume of water he measures is 74.51 ml</em>

Answer:

Null Hypothesis, $H_0$ : $\mu$ = 200 clicks a day

Alternate Hypothesis, $H_A$ : $\mu\neq$ 200 clicks a day

Step-by-step explanation:

We are given that a website developer wished to analyze the clicks per day on their newly updated website.

The website developer wants to know if the number of clicks per day is different than 200 clicks a day, on average.

Let $\mu$ = <u><em>mean number of clicks per day.</em></u>

So, Null Hypothesis, $H_0$ : $\mu$ = 200 clicks a day

Alternate Hypothesis, $H_A$ : $\mu\neq$ 200 clicks a day

Here, the null hypothesis states that the mean number of clicks per day is 200 clicks a day.

On the other hand, the alternate hypothesis states that the mean number of clicks per day is different than 200 clicks a day.

Hence, this is the correct null and alternative hypotheses.
