a school tracked the daily pollen count and the number
of absences for one month. it found that as the pollen count
increased the absences also increased.
Is there likely to be a correlation between pollen count and
absences? Will it positive and negative? Would a high correlation
suggest causation?

Expert Solution
Is there likely to be a correlation between pollen count and absences? Will it positive and negative?
ANSWER: From the given information
YES. There was positive correlation between pollen count and the absences.
Positive correlation: If both the variables are deviated in the same direction then the variables are positively correlated.
(OR) If one variable increases (decreases) then the another variable is also increases (decreases) then the variables are positively correlated.
Would a high correlation suggest causation?
ANSWER: NO
Even strong Correlation Still Does Not Imply Causation. But even if your data have a correlation coefficient +1 or -1, it is important to note that correlation still does not imply causation. A meaningful nonlinear relationship may exist even if the correlation coefficient is 0. Correlation and causation is, it's time to understand “Correlation does not imply causation”

10. A school administrator thinks that teacher absences are
equally probable for each day of the week. A co-worker does not
agree and gathers data from last year and reports the absences for
the day of the week in this table: Monday (46) Tuesday (47)
Wednesday (40 )Thursday (50) Friday (67) Test that the days of the
week have an equal probability of absences at the 0.10 level of
significance.
