A student calculates a 95% confidence interval for the mean height of plants based on a sample of 25 plants. The interval is [30 cm, 38 cm]. Later, she discovers that one of the measurements was recorded incorrectly as an outlier of 50 cm when it should have been 40 cm. How will correcting this single data point affect the center and width of the confidence interval?
