Find the P-value (to 4 decimals) for a x test with d. f. = 10 and STS X = 13 if the test is: %3D a. Left tailed: b. Right tailed: c. Two-tailed: Submit Question

The acceptable level for insect filth in a certain food item is 5 insect fragments (larvae, eggs, body parts, and so on) per 10 grams. A simple random sample of 50 ten-gram portions of the food item is obtained and results in a sample mean of x = 5.3 insect fragments per ten-gram portion. Complete parts (a) through (c) below. H = 5 (Round to three decimal places as needed.). o: = 0.316 (Round to three decimal places as needed.) (c) What is the probability a simple random sample of 50 ten-gram portions of the food item results in a mean of at least 5.3 insect fragments? P(x2 5.3) = (Round to four decimal places as needed.)

c= 0.98, o=7.3, and E= 1 Assume that a preliminary sample has at least 30 me n3= (Round up to the nearest whole number.) %3D

A sample of blood pressure measurements is taken for a group of adults, and those values (mm Hg) are listed below. The values are matched so that 10 subjects each have a systolic and diastolic measurement. Find the coefficient of variation for each of the two samples; then compare the variation. Systolic 117 128 158 94 158 120 114 138 124 1219 Diastolic 79 77 76 50 88 62 70 80 87 56 The coefficient of variation for the systolic measurements is %. (Type an integer or decimal rounded to one decimal place as needed.)

Round every calculation to 2 decimal points unless the specific question asks for something different. Show answers as decimals and not percents or fractions.

Apparently what I put was incorrect.

Hi! I need answers on letters A and B. Thank you! It would mean a lot.

The blood pressure in millimeters was measured for a large sample of people. The average pressure is 140 mm, and the SD of the measurements is 20 mm. The histogram looks reasonably like a normal curv Use the normal curve to estimate the following percentages. Choose the answer that is closest to being correct. A 19.1% B 30.9% C 38.2% D 69.1% E 68.27% A The percentage of people with blood pressure between 130 and 150 mm. B The percentage of people with blood pressure between 140 and 150 mm. D The percentage of people with blood pressure over 150 mm.
