The statement "Yes, all the conditions for Inference have been met" is correct.

A t-test is a hypothesis-testing technique for analyzing the means of one or two populations. A t-test can be used to see if a single group differs from a known value, if two groups differ from each other (an independent two-sample t-test), or if paired measurements show a significant difference.

We have:

Null hypothesis:H0: μ1 – μ2 = 0,

Alternative hypothesis: Ha: μ1 – μ2 < 0

As it is mentioned that the samples are drawn randomly and mentioned that no skewness is observed, this Indicates that the distribution is approximately normal

The total number of readings = 10

Which is not more than 10% of the Population size.

Thus, the statement "Yes, all the conditions for Inference have been met" is correct.

a) 4.4583 b) Fiona

Step-by-step explanation:

First find the average of the numbers by adding them all together then dividing them by the amount of numbers given:

$(85 + 88 + 90 + 91 + 93 + 96 + 97 + 97 + 98 + 98 + 99 + 105)\div12= 1137\div12= 94.75$

Then find the difference between each number and the answer you got

$(85 - 94.75) + (88 - 94.75) + (90 - 94.75) + (91 - 94.75) + (93 - 94.75) + (96 - 94.75) + (97 - 94.75) + (97 - 94.75) + (98 - 94.75) + (98 - 94.75) + (99 - 94.75) + (105 - 94.75)\div12$

Which is

$(9.75) + (6.75) + (4.75) + (3.75) + (1.75) + (1.25) + (2.25) + (2.25) + (3.25) + (3.25) + (4.25) + (10.25)\div12$

Which comes out to

$\frac{53.5}{12}=4.4583$
