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

<h3>What is a t-test?</h3>

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.

aleksandr82 [10.1K]

Answer:

Equation : 4(1,276) = p

That means that Ashely took 5104 pics.

Step-by-step explanation:

Before we come up with an equation we can solve the problem and see how we solved it. If Aaron had 1,276 pics and his sister took 4 times that, we would multiply 1,276 by 4 to get how many his sister took. We don't need to do the math, but that's how we would solve it. So to find p, or Ashely's amount of pics, it's just 1,276 times 4 = p

Equation : 4(1,276) = p

That means that Ashely took 5104 pics.

Please mark brainliest if possible and have a nice day! :)
