Hello, can I please have help on these problems.

At Rachel's 11th birthday party, 8 girls 1.Irere timed to see how long {in seconds} they could hold their breath in a relaxed position. After a 2-minute rest. they timed themselves while jumping. The girls thought that the mean difference between their jumping and relaxed times would be zero. Test their hypothesis. Relaxed time [seconds] Jumping time {seconds} a. Ha: risen It. H . a. In words, CLEARLY state what your random variable X or Pf represents. State the distribution to use for the test. 1Ii'lllhat is the test statistic? 1ll'lihat is the oualue? ln one or two complete sentences, explain 1.Ilrhatthe paralue means for this problem. Use the previous information to sketch a picture of this situation. CLEARLY, label and scale the horizontal axis and shade the region[s] corresponding to the pvalue. Figure E1 Indicate the correct decision (\"reject' or \"do not reject\" the null hypothesis}, the reason for it, and write an appropriate conclusion, using complete sentences. i. Alpha; ii. Decision: iii. Reason for decision; i'lul'. CD I'lCtUSiCIFII i. Construct a 95% confidence interval for the true mean or proportion. Include a sketch of the graph of the situation. Label the point estimate and the lower and upper bounds of the confidence interval. Figure E2
