On November 19, 2020, the New York Times (NYT) posted a figure online examining the association of the incidence of Covid-19 in the 50 US states and Washington, DC and its relationship to the strictness of new containment measures implemented in each state. Incidence is expressed as number of new cases per 100,000 residents (NEWCASES), and strictness was measured on a scale of 0 = no measures to 100 = complete shutdown of all activities and businesses (STRICT).

A version of the NYT figure is shown below. Labels for five US states are included, as well as a least-squares regression line.

Using our linear regression Excel spreadsheet from class, the data produce the following table of information:

Parameter	Estimate	Std Error	t-value	p-value
Intercept	127.57	16.00	7.99
Slope	-1.38	0.33	-4.21
