lisov135 [29]3 years ago
5 0

Answer:

10 units

Step-by-step explanation:

if we're trying to find the width of the arch, then essentially we're trying to find where the arch ends so we can calculate that width right.

you can do this by find the zero's

0 = - (x-5)(x+5)

x = -5,5

simply find the difference between these two values to get width = 10

Identify the conclusion in a hypothesis test of the following claim and sample data:
Anarel [89]

Answer:

C

Step-by-step explanation:

Firstly, we set up the null and alternative hypothesis as follows;

The null hypothesis is;

H0: μ ≥ 12

The alternative hypothesis is;

Ha : μ < 12

Next step is to calculate the test statistic z

Mathematically;

z = (x - μ )/ σ /√n

= (11.58 - 12) /1.93/√(80

Test statistic z = -1.92

Now we proceed to find the probability value that is equal to the value of the test statistic. We can find this by using the standard normal table or NORMSTD function on excel

P(z < -1.92) = 0.0274

P-value = 0.0274

alpha = 0.05

From the above, we can see that

P-value < alpha

And because of this, we are going to reject the null hypothesis and therefore accept the alternative.

We then conclude that there is sufficient evidence to conclude that "The average battery life (between charges) of this model of tablet is at least 12 hours."
