STATISTICS AND PROBABILITY (interpreting p values and confidence intervals from a table)

I simply need assistance answering the following questions clearly.

b) Consider again Aydin and Yalcin (2022). In Table 2, there is a line \"Biceps skin-fold thickness (mm).\" In that line, they report a p-value of less than 0.001. Give the null hypothesis of the test corresponding to that pvalue, in words and symbols, and give an apprOpriate conclusion that relates to the problem at hand. 0) Consider again Aydin and Yalcin (2022). In Table 2, the authors report a value of 11.1, with an associated condence interval of [10.0, 12.2]. Give an interpretation of the condence interval, in the context of the problem at hand. 3.2 Changes in maternal PAM in the first month after delivery Changes in maternal anthropometric measurements during the follow-up period are shown in Table 2. BMI decreased by a mean of 1.4 kg/m between the 5th and 30th days. At the end of the first postpartum month, maternal body weight (relative percentage change -5.1%), muscle mass ratio (-1.6%), body fluid ratio (-2.4%), waist circumference (-1.9%), hip circumference (-1.5%), and WHR (-0.4%) decreased, whereas fat mass ratio (10.3%), triceps skin-fold thickness (16.6%), biceps skin-fold thickness (29.0%), and mid-arm circumference (11.1%) increased (Table 2).
