Answer:
y = -7x + 9
Step-by-step explanation:
Point-slope form:
y - 2 = -7 (x -1)
y - 2 = -7x + 7
y - 2 + 2 = -7x + 7 +2
y = -7x + 9
Answer: x = 2.36
Step-by-step explanation:
Graphic solution is attached.
approximate solution is 2.36 according to the graph
Verifying the solution as asked:
x + 2 = x³ - 2x - 4
2.36 + 2 = 2.36³ - 2*2.36 - 4
4.36 = 13.14 - 4.72 - 4
4.36 ≈ 4.42
If we round to 4.4 it's clearer that this is the right solution.
The T statistic does not require any information about the population.
<h3>
What is T- statistic?</h3>
The T - statistic is the ratio of the predictable value of a parameter from its hypothesized value to its standard disputable values.
The T statistic uses the sample variance instead of the population variance.
Since, the T statistic depends on the hypothesized population mean. So in place of the standard deviation of population, size or mean of the population, T-statistic depends on the sample mean, the sample standard deviation and the sample size .
Thus, The T-statistic does not require any information about the population
