12:51 K A pediatrician wants to determine the relation that exists between a child's height, x, and head circumference, y. She randomly selects 11 children from her practice, measures their heights and head circumferences, and obtains the accompanying data. Complete parts (a) through (g) below. Click the icon to view the children's data. Data Table (a) Find the least-squares regression line treating height as the explanatory variable and head circumference as the response variable. y = x+ (Round the slope to three decimal places and round the constant to one decimal place as needed.)

T stat please An annual championship event is the most widely watched sporting event in a country each year. In recent years, there has been a great deal of interest in the ads that appear during the game. These ads vary in length with most lasting 30 seconds or 60 seconds. The accompanying data represent the ad length and ad scores from a recent championship. Complete parts (a) through (c). 30-Second Ads 60-Second Ads 48 27 40 39 47 65 59 58 60 53 40 23 36 53 54 24 39 38 47 61 a. Assuming that the population variances from the 30-second ads and the 60-second ads are equal, is there evidence of a difference in the mean score between the two types of ads? Use α=0.02. Let μ1 be the mean score for the 30-second ads and μ2 be the mean score for the 60-second ads. Determine the hypotheses. Choose the correct answer below. A. H0: μ1≥μ2 H1: μ1<μ2 B.…
