It's even better if you have a telescope or binoculars. Both allow you to see planets, the moon, and stars even closer. Telescop
es are more powerful than binoculars. With a telescope, you can see the moon close enough to see its features. Labeled images like this one can help you find different places on the moon or other objects in the night sky. Even without a telescope, you will still be able to find some of these place
What does this mean for you and your stargazing? Well, you may not make any major discoveries like Galileo did, but you can look up at the sky in your own backyard. You can see the moon and many of the same stars that early astronomers saw. You can even see planets. For example, this is an image of Venus, Mars, and the moon, as seen from Earth without a telescope or binoculars. It is amazing what you can find if you just look up!
What evidence does the author use to support the idea that a telescope is not needed to learn about Earth's moon?
A. Early astronomers saw many of the same starts without a telescope.
B. Looking up at the sky is enjoyable even if you don't have special tools.
C. You can see even more detail in the sky if you use a telescope.
D. You can see some of the features of the moon without a telescope.

Answer:
Step-by-step explanation:
Data given and notation
represent the sample mean given
represent the population standard deviation
sample size
represent the value that we want to test
t would represent the statistic (variable of interest)
State the null and alternative hypotheses.
We need to conduct a hypothesis in order to check if the true mean for the gasoline prices is lower than 1.25, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
If we analyze the size for the sample is > 30 but we don't know the population deviation so is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:
(1)
Calculate the statistic
We can replace in formula (1) the info given like this:
