"Using Python, code to find the smallest and largest planet mass (if known), and plot these as two curves against the year of discovery"

Basically looking to use data from an excel sheet where 'disc_year' and 'pl_mass' are columns of data; and code Python to find the maximum value of mass and the minimum value of mass for each year, then plot this as two curves. There are multiple planets for any given year hence multiple values for mass. Below is example of what data might be.

Example data: Mass - 5.5, 0.2, 6, 56, 209, 0.3, 44, 124, 403, 98, 304, 202, 11.7, 5.4, 17.8, 21.9, 603.3, 108.2, 19, 0.3

Year - 2019, 2019, 1994, 2002, 2001, 2016, 1994, 2019, 2002, 2001, 2016, 2015, 2015, 1999, 2002, 1999, 1999, 2015, 2001, 2016

7. The National Technology Readiness Survey sponsored by the
Smith School of Business at the University of Maryland surveyed 418 randomly sampled Americans, asking them how often they delete spam emails. In 2004, 23% of the respondents said they delete spam mail once a month or less, and in 2009 this value was 16%.

(a) What are the hypotheses for evaluating if the proportion of those who delete their email once
a month or less has changed from 2004 to 2009?
bb
(b) What is the point estimate for the deference between the two population proportions?

(c) A report on the survey states that the observed decrease from 2004 to 2009 is statistically
significant. Explain what this means in context of the hypothesis test and the data. (d) Would you expect a confidence interval for the deference between the two population proportions to contain 0? Explain your reasoning

Glen Avon Inc. specializes in the production of telecommunication satellites. The company has

a 6-month fiscal end on December 31 and June 30. In 2004 the company decides to expand their

operations and finances it by issuing 4,000 bonds at a 14% coupon rate (annual). The bonds pay

interest on October 31 and April 30, and are due on April 30, 2019.

a. (3 points) Assuming the bonds are issued on April 30, 2004 at 104, record the journal

entry(ies) for the issue.

b. (5 points) Record the proper adjusting entry(ies) for the 6-month fiscal end on June 30, 2004.

c. (4 points) Record the interest payment on October 31, 2014.

d. (8 points) On November 30, 2014, the company purchases 90 percent of the bonds back at

110 plus accrued interest. Record the proper journal entry(ies) for the repurchase.
