Use the calculator provided to solve the following problems. • Consider a t distribution with 13 degrees of freedom. Compute P(121.66) Round your answer to at least three decimal places. • Consider at distribution with 21 degrees of freedom. Find the value of c such that p(-c

Find the margin of error for the given values of​ c, s, and n. c=0.90​, s=3.3​, n=16 Use the​ t-distribution table. ​(Round to one decimal place as​ needed.)

Find to.20 for T distribution with 29 degrees of freedom. to.20 (Round the answer to 3 decimal places)

Find the value of t for the t distribution for the following. Area in the right tail = 0.05 and df =12 Round your answer to 3 decimal places. T=

In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer. i need help with (c), sketching the distribution, (d) and (e)

Find the value of t for the t distribution with a sample size of 30 and area in the right tail equal to 0.025 . Round your answer to 3 decimal places.

Find the z-score corresponding to the given value and use the z-score to determine whether the value is significantly low or high.  Consider a score to be significantly low if its z-score is less than  or equal to -2.  Consider a z-score to be significantly high if it is greater than or equal to 2.  Round the z-score to the nearest tenth if necessary. A body temperature of 96.7° F given that human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°.
