Answer:

Step-by-step explanation:

a. P(Z > 1.12) = 1-N(1.12) = 1-0.8686431=0.1313569

b. <em>P(Z S-2.35)</em> => P(Z <= 2.35) = 0.009386706

(please check interpretation of question b)

c. <em>POSZ s 1.34)</em> => P(0 <= Z <= 1.34) = 0.9098773 - 0.5 = 0.4098773

(please check interpretation of question c)

d. P(-0.8 sz s 2.44) => P(-0.8 <= 2.44) = 0.9926564 - 0.2118554 = 0.780801

(please check interpretation of question d)

Do the results support or contradict the common belief that the mean body temperature is 98.6degreesF? A. The results contradic

nata0808 [166]

Answer:

A. The results contradict the belief that the mean body temperature is 98.6 °F because both the mean and the median are less than 98.6 °F.

Step-by-step explanation:

Assume the temperature data were those in the table below.

You would have calculated that

Mean = 97.9 °F

Median = 97.9 °F

These observations contradict the belief that the mean body temperature is 98.6 °F.

A 2017 study found the mean oral temperature of more than 35 000 British patients was 97.9 °F.

If you save one penny on January 1, two pennies on January 2, three pennies on January 3, and continue this pattern for one year

monitta

The given condition is an arithmetic sequence with the first term (a1) is 1 penny and the common difference (d) is 1 penny. A year that is not a leap year has 365 days (n). The arithmetic series (S) is calculated through formula,

S = (n/2) (2a1 + (n - 1) x d)

Substituting the known values,

S = (365/2) (2 x 1 + (365 - 1) x 1)

S = 66795 pennies

A dollar is 100 pennies. Therefore, at the end of the year, the total savings is $667.95.
