ozzi

Answer:

It might be independent t-test.

Step-by-step explanation:

Basically it is a independent t- test .Independent sample test t - test or student test is a statistical test.In this test we determine that there is a statistically significant difference between the mean when we are talking about unrelated group.

We are taking alternative and null hypothesis t- test

In null hypothesis we see that population of two unrelated groups are equal

H₀: u1 = u2

if we reject the hypothesis and accept the alternative hypothesis than population means

H₁: u1 ≠ u2

In this test we need a significance level that is also called alpha level who reject or accept the null hypothesis.

Naomi starts running and James starts running 4 seconds later. Let t represent the number of seconds since Naomi started running
slega [8]

Answer:

J(t) = t-4

Step-by-step explanation:

Assuming that both Naomi and James keep on running, the number of seconds that James has been running will always be 4 fewer than the number of seconds that Naomi has been running (t). Therefore, expression (J(t)) that represents the number of seconds James has been running is:

J(t) = t-4
