Does the sample data support the conclusion that the mean iq of soccer players who frequently head the ball is lower than that of those who do not frequently head the ball? test the relevant hypotheses using α = 0.05. (use a statistical computer package to calculate the p-value. use μfewer than 10 headers − μ10 headers. round your test statistic to two decimal places, your df down to the nearest whole number, and your p-value to three decimal places.)

The reflexive property of congruence lets you say that ∠pqr ≅

Me max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
