Gina believes that less than 60% of the seedlings will record a growth of 3cm. The researchers believe otherwise. After a month, they selected 225 seedlings at random. 149 of those had grown more than 3cm. At alpha = 0.05, is Gina's estimate valid? The resulting test statistic exceeds the critical value. We cannot sag.r that Gina's estimate is invalid. The researchers' hypothesis is the null hypothesis. The resulting test statistic exceeds the critical value. We can sayr that Gina's estimate is invalid. The researchers proved her wrong
