Question

select spin to start the spinner. spin the spinner 90 times to simulate the 90 - day weather forecast. which type of weather has the lowest observed frequency? 90 - day weather forecast

result	predicted frequency	observed frequency
rain	18	0
clouds	27	0
sunshine	36	0
total	90	0	o wind o rain o clouds o sunshine spin

Explanation:

Step1: Check observed frequencies

From the table, the observed frequencies for wind, rain, clouds and sunshine are all 0. But looking at the predicted - frequency values for comparison (as the observed frequencies are all equal here), the predicted frequency of wind is 9, which is the lowest among the predicted frequencies of the four weather types.

Answer:

wind
