Heights​ (cm) and weights​ (kg) are measured for 100 randomly selected adult​ males, and range from heights of 135135 to 193193 cm and weights of 3838 to 150150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x overbarxequals=167.72167.72 cm, y overbaryequals=81.4981.49 ​kg, requals=0.2570.257​, ​P-valueequals=0.0100.010​, and ModifyingAbove y with caretyequals=negative 107−107plus+1.141.14x. Find the best predicted value of ModifyingAbove y with carety (weight) given an adult male who is 187187 cm tall. Use a 0.050.05 significance level

A student wishes to determine the average life-span of a household light bulb. She randomly collects 15 light bulbs. The issue that may arise from her survey is…    The bias will be high. The accuracy will be low. The precision will be low. The standard error will be too low.

Taylor Swift is interested in learning what proportion of her fans want her to re-record her masters, so she takes a simple random sample of 500 fans and asks them.  Of the 500 fans, 487 of them (97.4%) respond that they want her to re-record all of her masters.  What is the parameter and what is its value?   a. The parameter is the average number of all Taylor Swift fans who want her to re-record her masters, which is unknown.   b. The parameter is the proportion of the sampled Taylor Swift fans who want her to re-record her masters, which is unknown.   c. The parameter is the group of the sampled Taylor Swift fans who want her to re-record her masters, which is 487.   d. The parameter is the proportion of the sampled Taylor Swift fans who want her to re-record her masters, which is 0.974.   e. The parameter is the proportion of all Taylor Swift fans who want her to re-record her masters, which is unknown.   f. The parameter is the proportion of all…

A researcher found that the two groups (n=25 in each group) they tested were significantly different from each other with a t-value of 2.91, which has a corresponding p-value of p=.06. Report the findings in APA number format.

Let the height data (105)represent sample. Use an appropriate statistical test to check whether the population mean is different from 170 cm.Use α = 0.05.Also, write a substantive conclusion and explanation. Use an appropriate graph to check if data is normally distributed. Do it in R commander.

Suppose that 50 measurements were taken and the mean was calculated to be 4.55. Assume next that one of the data items was 19.4This was assumed to be an outlier as was discarded. What would be the mean of the remaining 49 numbers? I

Can you solve for the p-value and is H0 rejected or not rejected?

A student scored between 81% and 93% on all exams except for one that she failed with a47% because she studied the wrong chapters. Which value would better represent hertypical performance: mean exam grade or median exam grade? Briefly explain.

1.) Write your solution A. Determine the 1" quartile, 2 quartile, 3rd quartile and interquartile range (IQR), given the scores of; 11, 24, 23, 11, 13, 17, 15, 19, 21, then interpret each of your answer. B. Solve for the Percentile Rank of 17.
