Question

Sunspots are relatively "cool" regions on the sun that appear as dark spots when observed through special solar filters. The number of sunspots varies in an 11 -year cycle. The table gives the average daily sunspot count for the years 1975-2004 (a) Make a scatter plot of the data. year sunspots year sunspots 1975 16 1990 143 1976 13 1991 146 1977 28 1992 94 1978 93 1993 55 1979 155 1994 30 1980 155 1995 18 1981 140 1996 9 1982 116 1997 21 1983 67 1998 64 1984 46 1999 93 1985 18 2000 119 1986 13 2001 111 1987 29 2002 104 1988 100 2003 64 1989 158 2004 40

Answer 1

To make a scatter plot of the sunspot data, plot the year on the x-axis and the sunspot count on the y-axis. Connect the data points to show the trend.

Step-by-step explanation:

To make a scatter plot of the data, you will plot the year on the x-axis and the average daily sunspot count on the y-axis. Each data point will represent a year and its corresponding sunspot count. Here are the steps to create the scatter plot:

1. Create a coordinate plane with the year range of 1975-2004 on the x-axis and the sunspot count range on the y-axis.
2. Plot each data point by locating the year on the x-axis and the sunspot count on the y-axis. For example, the first data point is (1975, 16).
3. Repeat step 2 for all the data points.
4. Once all the data points are plotted, connect them with a line or leave them as individual points, depending on your preference.
