Answer: 12 only
Step-by-step explanation:
The given graph is representing the function f(x).
To find the value of f(0), we need to check the position of curve at x=0.
It implies we need to check the position of curve on y-axis.
We can see there is only one point where function curve is intersection the y-axis such that at x=0 .i.e. y=12
Hence, from the given graph the value of only.
Using the t-distribution, it is found that the correct option is:
0.005 < P-value < 0.01, reject the null hypothesis.
<h3>What are the hypothesis tested?</h3>At the null hypothesis, it is tested if the mean of a given population is equal to 85, that is:
We have a left-tailed test, hence, at the alternative hypothesis, it is tested if the mean of the population is less than 85, that is:
The test statistic is of t = -3.018.
Using a t-distribution calculator, with test statistic t = -3.018, 13 - 1 = 12 df and a significance level of 0.01, it is found that the p-value for a left-tailed test is of 0.0051.
The p-value is <u>less than 0.01</u>, hence the null hypothesis is rejected and the correct option is:
0.005 < P-value < 0.01, reject the null hypothesis.
