The information that the student can determine is that;

<em><u>Option A; The sample is not a heterogeneous mixture.</u></em>

The missing options are;

A.The sample is not a heterogeneous mixture.

B.The sample is not a homogeneous mixture.

C.The sample is not a compound.

D.The sample is not an element

We are told that the sample of matter given to the student is uniform in colour and texture.

A homogeneous sample has uniform composition and it is possible this may be one too.

A compound is also uniform in it's composition and this sample could be a compound.

An element also has a uniform composition and the sample may be an element.

Lastly, a heterogeneous sample does not have uniform composition and as such, this sample is definitely not a heterogeneous sample.

Do collaborators believe people will perform their tasks to the best of their ability true or false
marta [7]

Answer:

The answer is true.

Explanation:

In order to learn more about the answer, let's define what collaboration is.

Collaboration- <em>this is a working practice whereby individuals work together in order to achieve a common business purpose.</em> It relies on openness and knowledge sharing. It also includes some level of focus and accountability on the part of the business organizations.

Question
Ghella [55]

Answer:

0.456

0.324

Explanation:

The null and alternative hypothesis :

H0 : p = 0.40; HA :p < 0.40

Test statistic :

(Ph - P) / sqrt[(p*(1-p))/n]

Ph = X / n

X = 34 ; n = sample size = 80

Ph = 34 / 80 = 0.425

(0.425 - 0.4) / sqrt[(0.4(0.6)) / 80]

0.025 / sqrt(0.003)

0.025 / 0.0547722

Test statistic = 0.4564359

Test statistic = 0.456

Using the P-value from Zscore calculator :

Significance level of 95% ; one tailed

Z statistic value = 0.456

P value = 0.324195

= 0.324 ( 3 decimal places)
