For x-intercept,
y = 0,
log(3x+3) = 2
(3x + 3) = antilog(2)
x = (antilog(2) - 3)/3
x ≈ 32.3333
For y-intercept,
x = 0,
y = log(3) - 2
y ≈ -1.5228
Answer:
It does not appear that, as a group, the students are reasonably good at estimating one minute.
Step-by-step explanation:
We are given the following data in the question:
75, 88, 51, 73, 49, 31, 69, 74, 72, 59, 72, 81, 99, 101, 73
Formula:
where are data points,
is the mean and n is the number of observations.
Sum of squares of differences = 4739.733
Population mean, μ = 60 minutes
Sample mean, = 71.13 minutes
Sample size, n = 15
Alpha, α = 0.10
Sample standard deviation, s = 18.39 minutes
First, we design the null and the alternate hypothesis
We use Two-tailed t test to perform this hypothesis.
Formula:
Putting all the values, we have
Calculating the p-value from the table, we have,
P-value = 0.034354
Since the p-value is lower than the significance level, we fail to accept the null hypothesis and reject it. We accept the alternate hypothesis.
Thus, we conclude that it does not appear that, as a group, the students are reasonably good at estimating one minute.
You should plot the total distance traveled from the base camp on the x-coordinate while the elevation should be plotted on the y-coordinate.
<h3>What is a graph?</h3>A graph simply refers to a type of chart which is commonly used to graphically represent data on both the vertical and horizontal lines of a cartesian coordinate (x-coordinate and y-coordinate).
<h3>How to plot this graph?</h3>In this scenario, you would plot the total distance traveled from the base camp on the x-coordinate while the elevation of the camps would be plotted on the y-coordinate as shown in the image attached below.
