Question

I want to know the answer and details step by step

Thank you so much

In this question, we will set up and test the appropriate hypothesis for verifying a claim from
astronomy.
The Bubble space telescope is an optical telescope that was launched into space in
1990 to collect data from distant stars and glaxies, and has proven to be an
invaluable source of information to many astronomers and cosmologists.
• Recently, a team of researchers from NASA led the design and development of the
Webb space telescope, which was claimed to be capable of higher resolution images
and less error-prone in comparison to its predecesor, the Bubble space telescope.
In order to lend credence to the claim that the newly designed Webb space telescope was
capable of more accurate measurements compared to the Bubble space telescope, the
scientists from NASA were required to show sufficient evidence for this claim in a
formal statistical setting.
In order to test the hypothesis that the measurement error from the Webb telescope was indeed smaller
than the measurement error from the Bubble telescope, the researchers designed the following
experiment:
A collection of n and m observations were taken of a fixed object in the observable universe by, the
Bubble telescope and the Webb telescope, respectively.
Let
iid
X1, X2,..., X₂ N(μ₂0²)
denote the collection of n observations taken by the Bubble Telescope, and let
iid
Y₁, Y₂,..., YmN(μ, o})
denote the collection of n observations taken by the Webb Telescope. The mean is the true
(unknown) brightness of the object, and the (unknown) variances and a represent the
measurement error from the Bubble and Webb telescopes, respectively.
Using this information, answer the following questions:
